Why has Martin Heidegger assumed such proportions as a thinker, especially for Catholic theologians? Is it because Heidegger's concern with being seems so close to our own – so close to Erich Przywara's analogia entis, so close to what we have been taught St. Thomas Aquinas said of God and being? Is not being the foundation of everything, and is the promise that Heidegger will help us show how this might be? How could he undertake this task – this excoriating critic of Church Doctrine (die Kirchenlehre)– Catholic or protestant – who announced, even before he wrote Sein und Zeit, that with him and following Nietzsche, “philosophical research is and remains atheism”.Footnote ²

What do Catholics want to say of being? It could not be summed up better than by the Holy Father in the recent encyclical letter Fides et Ratio when he says that the intellectus fidei itself demands the assistance of a philosophy of being.Footnote ³ Moreover, are we not prompted in this direction by the Holy Father's other statement in Fides et Ratio concerning St. Thomas Aquinas and in connection with how a philosophy of being unfolds, that “his is truly a philosophy of being and not merely of appearing”.Footnote ⁴

Catholics especially who have wanted to engage with the work of Martin Heidegger – and I can think of two pre-eminent examples in Jean-Luc Marion and Vittorio Possenti (whilst not forgetting Jean-Yves Lacoste, Ghislain Lafont, Johannes Lotz among others, but Marion and Possenti especially because of their desire to confront the postmodern reception of Heidegger), have experienced his work as a kind of limit, almost a ban on what they assume Heidegger has insisted may not be said in the light of his researches. This is exemplified by Marion's reading of Heidegger's comments at the very heart of this question of the relation, not just between theology and Heidegger, but where Heidegger himself seems to place it – between himself and St. Thomas.

Why does Heidegger place the relation here? Is it because this is in fact where he finds we have already placed it? Is it, rather, because of the most fruitful engagement of St. Thomas with Aristotle, where St. Thomas always refuses the name philosopher for a Christian, only ever willing to cede this lofty title above all to Aristotle, and then to pagan or at least non-Christian authors?Footnote ⁵ In this case, is Heidegger seeking to draw our attention to a limit already set for us by one to whom we are already looking, and yet we overlook a limit that Aquinas himself had set? How can we dare to criticise and expose the violence done to theology as sacra doctrina in the wake of Hegel and German Idealism's fusion of philosophical and theological tasks unless we recover the limit that Aquinas took for granted as necessary – that is, that it was not reason that was at issue, so that all could fall under the sway of reason and be suborned to its requirements. Reason, ratio, thinking, , only brings the self to the fore as a theme, a self which even when taken hold of adequately as the proper task of philosophy still is required to be redeemed. Thus St. Thomas distinguishes between philosophical contemplation, which is pursued through a loving of the self, and Christian contemplation, which is contemplation of God.Footnote ⁶

Thus in the so-called Zürcher Seminar of 1951, Heidegger is asked: “May being and God be posited as identical?”.Footnote ⁷ Heidegger's reply to this question is full of teasing, full of a dry, acridly ambiguous humour that plays with our own mishearings. He says that the answer hangs together with the “Europeanisation of history”, and that being and God are not identical, and I would never attempt to think the essence of God through being”. He concludes I think very modestly about being with regards to its use to think the essence of God”.Footnote ⁸ Marion concludes from this: “A single indication comes to us: the word being must not intervene in a theological discourse”.Footnote ⁹

Vittorio Possenti has proceeded in the opposite direction to Marion, seeking not to erase being from God, and therefore to erase God in the places of being, but rather to take up and defend the term ‘ontotheology’. Possenti says “the criticism of ontotheology and of analogy, taken for granted as a commonplace in many currents of thought, is usually developed by adopting Heidegger as an inspiration”.Footnote ¹⁰ Pointing to the very passage in the Zürcher Seminar that Marion examined as proof of his contention against Heidegger, Possenti argues for ontotheology and what it names, and says: “Only thinking God as Esse can one perceive the difference between being as esse and being as ens. This enormous development escaped Heidegger, who even here was unable to avoid the oblivion of being”.Footnote ¹¹ Possenti names a gallery of authorities for his claim – Maritain, Augustine, Anselm, Bonaventure, and of course, Aquinas.

Let us set aside for the time being Possenti's apparent ignorance of the fact that it was Heidegger himself who coined the term ontotheology, specifically in relation to the metaphysical triumphalism of the Hegel who sought to subsume the God of faith under the unfolding of the metaphysics of absolute Geist, or that the term analogia entis has no lengthy genealogy, and that it was von Balthasar himself who asserted it never existed as a formal principal before Erich Przywara's work of the same name turned it into one.Footnote ¹² Rather let us note that these two eminent Christian thinkers, who are in complete agreement amongst themselves about the extent to which Heidegger is the fomenter of the nihilism of our present situation, nevertheless proceed for their solution in entirely opposite directions. If one seeks to eradicate being from theological speech, the other rejoices in a triumph of their identity so escalated that God himself alone will authorise the meaning of the term being.

Let us begin to unravel this seeming paradox by asking the question which Heidegger himself points us to, and which deserves an answer: does thinking demand that God and being are the same? Indeed, let us ask it even as Heidegger asks it with regard to faith: did Aquinas think that God and being are the same? Surely the method to be employed here – the method of either Lotz or Caputo, for instance – is that we simply examine what Aquinas says being is, and what Heidegger says being is, and then compare them.Footnote ¹³ And because we are good Catholic thinkers, we will of course discover that Aquinas is right and Heidegger the ‘nihilist’ wrong, and so all will return to a certain equilibrium in our lecture-rooms and within the Church. Except that both Heidegger and the Holy Father pose to us a question which, if we were to overlook it, would mean that our work never had any significance outside our universities nor even in our churches and the Church, and so the mission of the Church would remain unfulfilled precisely because of our inability to see further than the farthest tip of our noses. For Heidegger says, as I have already indicated, that this has something to do with the whole place of Europe in our history. The Holy Father says nothing less when he reminds us that: “Philosophy […] arose in Greece and is therefore Eurocentric”.Footnote ¹⁴ This is not to say that other nations and places do not each have a genius of their own –Fides et Ratio is most careful to assert that they do, nor even that Greek philosophy is the philosophy of the Church – it is not, and anyway, she has none such.Footnote ¹⁵ Rather, the history of thinking itself, both before, within, and alongside the Church is not accidental and is itself inter-twined with the ongoing work of revelation. Our history has not fallen out accidentally, but we have emerged in pilgrimage from a particular place, and the journey has itself been part of the content of the pilgrims’ way.

In the question of how we take up the ‘philosophy of being’ something is at issue, in the balance, and cannot simply receive a ‘final’ or ‘decisive’ answer that allows us a certain sleepiness with regard to what it poses. It is overlooking this, the ‘danger’ and ‘emergent need’Footnote ¹⁶ that Heidegger himself so often adverted to, and that we too have begun to become awakened with all our bandying around of the term ‘nihilism’ like some playground insult (as if calling people names would reform for them the way they live their lives). Forgetfulness of being is also an issue of danger for men and women of faith, and for the life of faith itself. Do we dare overlook the extraordinary thing that our forebears took for granted, that the richest veins of Christian reflection emerged from a period that was itself among the richest in Europe's life of thinking – or that now, when everything has been turned into consumption and technique, we are consumed by the very things we delight to consume, and what we know grows daily less and less able to motivate us to lives worth leading, even though full to the brim of distractions from the anguish of that emptiness, so that now faith seems everywhere in threat of ruin? Are we Christians so exempt from the depravities of the market, so recluded from the raging fire of the consumer society? Or are we not ourselves as much a product of it as anyone else, though struggling to know what faith has to say in the midst of this tide of meaninglessness. A philosophy of being must be posed as a question about what it means for us as beings to be– to be living beings in the places in which we find ourselves. It can never descend to the level of metaphysical niceties and comforting thoughtfulnesses, nor denunciations intended to hold back a tide of nihilism that has long since engulfed far more than just our ankles.

For our first indicator of how we might take up this question, should we not be surprised that Possenti and Marion can proceed in opposite directions from the very same passage they each examine of Heidegger's work? Or, indeed, is that even what they do? For it seems to me that both take one thing for granted, which is that being is to be taken as ground – as foundational, and that this ground is, as Possenti says “a universal all-pervading First Cause, which at every moment activates every created existent”.Footnote ¹⁷

Do we then doubt with Heidegger, that God is first cause? Except that Heidegger says that without doubt, without the possibility of unfaith, faith is not faith.Footnote ¹⁸ Heidegger argues that the opening words of Genesis, “in the beginning God created the heavens and the earth”, are the matter of faith, not philosophy. Once Christian faith has been admitted, then we may speak of God as the cause of all things. Heidegger asks at this point however, do we in faith still need to configure God to being?Footnote ¹⁹ In posing these questions he is in remarkably good company, above all with St. Thomas himself. Aquinas certainly does not believe that for God, God is the (temporal) prior cause of all things. God is not ‘prior’ to creation in that sense. This sense of temporal priority emerges only with Descartes and Newton, in a line which, no matter how much for each of them it testified to the place of God in creation, nevertheless led straight to Deism via the Arianism which Newton and his theologian Samuel Clarke were rightly accused of. God is only prior for us, for God, God is immediately contiguous with every temporal moment in creation.Footnote ²⁰ Even here, however, Aquinas exercises great caution. He begins his discussion De æternitate mundi with the statement that we suppose that the world has a beginning of its duration because this is what is in accord with the Catholic faith.Footnote ²¹

The Holy Father notes that “as a consequence of the crisis of rationalism, something akin to nihilism has appeared”.Footnote ²² It is in this context that a ‘philosophy of being’ must be undertaken. To what extent, therefore, must any future philosophy of being take into account and work through Martin Heidegger's understanding that the discipline and practice of metaphysics has and holds within itself and from its very outset in Plato the propensity towards the very nihilism which comes to prevail in the history of philosophy. Heidegger captures this in a sharp and provocative phrase that spans almost the entire history of philosophy in the West: “The metaphysics of Plato is not less nihilistic than the metaphysics of Nietzsche”.Footnote ²³ Why, in the light of this, is it constantly asserted that Heidegger is himself nihilistic? In other words, why is what Heidegger himself is in fact trying to expose and bring to understanding and to light exactly what time and again he is himself accused of carrying out?

In the light of these considerations I want to examine three questions in turn that may suggest exactly what it means to experience the limit to which Heidegger is attempting to draw our attention, while at the same time disposing of the limits that we experience. The three questions are: first, what indeed is a philosophy of being and what has God to do with it?; second, what does it mean to say that God = Being, and that this is a truth to be taken philosophically?; third, what does it mean to say that the word being must not appear in any future theology?

Neither Marion, nor Possenti, nor indeed anyone who has argued that Heidegger is in any sense a nihilist has understood the extent to which Heidegger's critique as a critique of the entirety of the whole of metaphysics does not seek to ‘eradicate’ or ‘eliminate’ the tradition of unfolding questions that metaphysics represents, but rather he thinks that this tradition must be understood and experienced in its fullness in the very working out of the question concerning being.Footnote ²⁴ This experience is in fact our confrontation with nihilism – it is our own need to pass through nihilism in order to find our way to the question of the ground, the basis, the very foundation of being.Footnote ²⁵ The guiding question of metaphysics has consistently been –‘what is the being?’, insofar as it is a being. Heidegger describes this as the ‘Leitfrage’, the guiding question of philosophy.Footnote ²⁶ Metaphysics answers this question always without reference to the being for whom the question arises, for whom the question is its own concern. The question therefore becomes asked in terms of highest being, that which is most stable, most present, most permanent about beings. The being which above all possesses life, is without death and at the same time without movement and which always ‘is’ in its being is, as early as Aristotle, understood to be God.Footnote ²⁷The being of every particular being, of being taken in the broadest and most general sense, is the making possible of this being here, what is most ‘beingful’ about it. This understanding of being, from the divinity of the idea of ideas, the in Plato to the eternal recurrence of the same as the permanentising of pure presence in Nietzsche is, for Heidegger at least, the metaphysical understanding or concept of God. Such an understanding of being, however, only asks about the particular being, , ens, in its being, without reference to the being for whom the very question is a question, the being of being human.

In this regard Possenti (but it is equally possible to make the same case with regard to Marion, and I have done so elsewhere)Footnote ²⁸ completely misunderstands Heidegger. Possenti suggests that Heidegger never takes into account with regard to the disclosure of things the “to whom?”Footnote ²⁹ things are disclosed with regard to truth. Struggling to reconcile the difference between truth as adæquatio in metaphysics and truth as , disclosure, in Heidegger, Possenti is forced to bring to the fore what he refers to as the ‘bridge’ that must exist between the realm of thought and the realm of the real, concluding that for Heidegger (whom he conveniently turns into a kind of Kant): “Nevertheless the nature of such a bridge was not reached”.Footnote ³⁰

Heidegger argues that the guiding question of metaphysics, , in the overcoming of metaphysics brings to the fore the grounding question – the question of that being for whom the guiding question can become, and historically is, a question, as a question that brings the being of the one asking the question before him or herself as a question. Such bringing-to-the-fore exposes, not the to-whom which Possenti seeks, which produces (in consequence of Descartes and Kant) the subject-object distinction, subjectivity as such, where subjects address and are addressed by objects which stand-against (Gegenstand, ob-iectum) them. Rather the the guiding question calls forth the for-whom, the ground of the one asking the question. This is not the subject, but the ground, the very basis of being itself, and so of any question concerning being. For Heidegger the first being for whom being is an issue turns out to be, not the self-in-general, the subject, but my-self, to whom I can never become an object, but for whom I am always primarily concerned.

However, the ground as such is not the self, but rather the there(Da) wherein the self takes up its place and finds itself, not seeking to constitute the bridge between itself and other subjects (to whom it is an object, and whose ‘to whom’ also produces others as objects), but finding myself already together-with, alongside, enbridged-to, others. In the construction of Possenti's bridge between the realm of thought and the realm of the real – between subject and object (but exactly as Marion has attempted to do in his investigations of Husserl's phenomenology, whilst already taking into account the question of the wider context of the realms within which subjects and objects appear)– what is really at issue is the character of bridging itself. Heidegger himself refers to this as the yoke named in Plato's Republic, in the allegory of the cave. Heidegger says that Plato asks: “What makes the thing seen and the act of seeing what they are in their relation? What spans the gap between them? What yoke () holds the two together?”.Footnote ³¹ In the allegory, the sun supplies the yoke, but as a figure for an idea. Not any idea, but the idea of ideas itself, the . Moreover, the allegory of the cave arises specifically after Plato has drawn attention to the connection between the sun as the making possible the visibility of all things and its fundamental connection with divinity.Footnote ³² Thus the bridge, which is itself an aim to be constructed and produced, always poses the question of transcendence. Truth, therefore, and strictly speaking, is the consequence of this constructing event.

What happens when it can no longer be taken for granted that the yoke holds the divine at its end – what happens, in other words, when Nietzsche's proclamation of the death of God becomes just that way in which we take it for granted we may think? Is the yoke disassembled? Or is it not rather that we become the ones on whom the assembly of the yoke depends? We estimate, value, evaluate, the truth of the beings that appear. Because we have placed God in this relation to truth, as truth's guarantor, do we not thereby place ourselves in the place of God when it is taken for granted that God is dead? Is the situation not even worse for those of us who then pit ourselves against this universalisation of the death of God, we Christian philosophers who will not let this god become a corpse? Do we then not have to resurrect constantly the god at the far end of the yoke, and do we not thereby transform our thinking into a productive will to power, which must then at every moment reproduce the god who must not be thereby allowed to die, even though already taken for dead in every other corner of thought apart from ours?

Is this not what Possenti’s, and Marion’s, (and John Milbank’s, for that matter) constant denunciations of nihilism have come to? For what is more annihilating than a dead god brought back to life for the sake of the health of truth? Indeed, I would go even so far as to say that our liturgy is now in danger of transferring this fundamentally metaphysical position to the very heart of Christian life itself, for do we not now to some terrible extent understand ourselves to be theurgically and productively making God present to ourselves instead of allowing the liturgy to draw us into the sacrificial presence of the one who alone might save us? Possenti's observation, that Heidegger does not complete the bridge (by which he means, refuses to place God at the end of it, refuses to make truth a bridge to the being of God) is quite accurate, but he has missed the force of Heidegger's critique.

Heidegger's argument is at this point, I think, extremely difficult to understand, because it requires an inversion of what we normally take, and have always been taught to take, as the case. The god of metaphysics is, Heidegger says, ‘constructed’, and exists out of what he calls “Machenschaft”: “In machination there lies at the same time the Christian-Biblical interpretation of beings as ens-creatum, irrespective of whether this becomes taken in a religious or secularised way”.Footnote ³³ Heidegger's point is that something belonging to revelation, to faith as such, has now become operative in metaphysics, in such a way that it no longer matters whether faith is present, but remains at work even in an entirely secularised context. We reach this god by virtue of completing the bridge which thereby brings us to understand this god already to be there, at the end of the bridge or yoke that holds the ideal and the real together. This is exactly the structure of Descartes’ subject: the self, having demonstrated its indubitability to itself, then proceeds to discover by taking up an aim, by a constructive process, a self-making as self-disclosing, that only the greatest, highest, most infinite being could have made this indubitable self possible in the first place. God is thereby made dependent on the secured indubitability of the self. An intentional aim, a trajectory, the working-out of the existence of the bridge or yoke brings this to light.Footnote ³⁴ When the understanding of God to which Descartes was able to make immediate and unthinking appeal is no longer operative, then (metaphysically) the god who made each of us as an ens creatum must itself be re-created, even if thereby posited in its recreation as already-creating. Creativity, , these are the dominant modes of truth within which the god of metaphysics is able to come to light. Such a god need have nothing to do with the God of faith. However, the will – either the will of the god of metaphysics to create us, or our creative will which replaces this dead god and so resuscitates it – becomes paramount. The will becomes the constitutive dominant mode of the unfolding of and .

Read like this, Heidegger's refusal of the bridge or yoke looks like a failure of the will. What, then, of my assertion that for Heidegger no yoke needs to be brought to light because he seeks to unfold the grounding question – the question of the ‘for whom?’ in asking who is it for whom the question has been the leading question, the bringing to light of the being of being-human wherein I find myself already together-with, alongside, others? If we simply transfer to this question the setting up of an aim, an intentional structure, then this ‘for whom’ will simply become the construction of other subjects, others alongside me whom I will come to discover.

My suggestion is that this is nothing other than the intersubjectivity which is so popular, especially among contemporary Catholic theologians – not least because of all the baggage of ethical imperatives that these interpolated subjects bring with them. Heidegger's question is different, and requires no aim, but rather requires that I discover myself already alongside, already together-with. It is here that the question of the place(the Da of Da-sein) wherein the question of being is asked – and here he means the – is raised. The is that which is already present, already the place wherein the grounding question of the ‘whom’ with regard to being is situated. In intersubjectivity this site has constantly to be constructed and produced, it is never taken as already-present. The however is not a construct, but is, as that place wherein I find myself already in being. Being-together-with is something which has to be demonstrated and unfolded – brought to light, not produced or constructed.

In Sein und Zeit Heidegger undertakes this demonstration with recourse to time: Miteinandersein, Mitsein(being-with-one-another, being-with) is disclosed through the fundamental temporal structures of Dasein. There is, however, a structure which Heidegger says is itself the originary ground of time as such: he makes this remark in two places: one, some fifteen years after the publication of Sein und Zeit. Here he says: “In Sein und Zeit, no matter how strange it must sound, ‘time’ is the given name of the originary ground of the word”.Footnote ³⁵ Speaking, and being held by the word as such, is the timing of time, or put another way, our belonging together and already being-with-one-another is itself disclosed by our being-speaking.

This may sound suspiciously like a ‘later’ Heidegger who has abandoned the structural analytic of Dasein for the thinking of being itself, however this view would be completely inadequate, for the other place where Heidegger makes explicitly the same point is in his 1925 lectures on Plato's dialogue, the Sophist. Here he shows that, for Aristotle and for Plato (indeed he argues that in this regard Plato is himself in this part of the Sophist[260a–268d] commenting on Aristotle!), speaking, , in its relation to rest and motion, and , brings the possibility of a philosophical determination of rest to light, as the , “das Immerseiende”, being-always.Footnote ³⁶ He concludes: “Thus you see, that in this concept of permanence, of the perpetual, factually, although not expressly, but according to the matter itself, for Plato the concept of time emerges, as the phenomenon which determines beings in their being: the present, which is often simply shortened simply to . And , the addressing disclosure of beings, is nothing other than the making-present of the visibility of beings themselves and therewith that in them as what it is; as presented disclosure it brings the present to appropriation”.Footnote ³⁷

It is possible to see here in its very root both the fundamental connection with God and why, curiously, in the whole of these lectures, Heidegger shies away from commenting on it. For toward the end of the Sophist the Stranger is keen to point out to Theaetetus the connection between this determination of speaking, , and divinity. The connection, however is established in the dialogue through , through the making-creating which Heidegger seeks to resist, and which becomes established by the way in which the , being-always (sempiternity), is secured.Footnote ³⁸ What is central for Heidegger, however, is the way in which Plato brings something to light which already lay as the grounding possibility for being itself: not , speaking as such, but (the middle voice), speaking-together-with, where there is one speaking with me always implied (even in that speaking-together-with which I undertake when I speak to myself ‘in the soul’ as Aristotle says): conversatio in Latin, being turned-together-towards. He avoids the question of divinity, not because it is not relevant, but because he himself believed it to be also disclosed for us in a different way: not as the sempiternal, but as what also belongs in its disclosure (but insofar as it is disclosed) to the being of being-human. Speaking-together-with, which discloses the fundamental temporal structures of Dasein is, at the same time, only disclosive of these structures because it simultaneously discloses human Dasein's being in the world. Thus speaking-together-with turns out at the same time to be indicating the world as the world that it is – in Greek, . Thus Heidegger says: “, in which the possibility of speaking, is a constitutive determination of Dasein itself, which I prefer to indicate through ‘being-in-the-world’, ‘being-in’”.Footnote ³⁹

Precisely because being is primarily concerned with world, and speaking is primarily concerned with the truth of being, it cannot have the specific reference to God that traditional metaphysics wants to give it. (It is silence that is proper to the place of God, not speaking.)

To understand how this is, and indeed, how it might relate to St. Thomas, we have to move on to the question of why the analogia entis becomes the weapon in the hands of those who sound the battle-cry against nihilism. To take our second question, ‘what does it mean to say that God = Being, and that this is a truth to be taken philosophically?’, I defy Vittorio Possenti or anyone else for that matter to show me the passage in St. Thomas Aquinas where he simply says, or intends, anything like ‘Deus est esse’. It is possible to find in Eckhart, in the Opus Tripartitum the expression “Esse est Deus”, but this is a quite different statement, and needs to be measured against Eckhart's understanding that in God knowing is prior to being.Footnote ⁴⁰ St. Thomas says that God is the actus essendi as actus purus,Footnote ⁴¹ and that Deus est suum esse.Footnote ⁴² Neither of these statements say that God = Being.Footnote ⁴³ It is here that Possenti, Marion, and many others have invoked the analogia entis as a way through. Being unites God and creation analogically, not univocally. This has, I believe introduced a huge confusion into theological thinking. In the first place, I do not believe St. Thomas ever thought that analogy was particularly important for the development of Christianity's engagement with philosophy. The word analogia only appears a handful of times in the two Summas and elsewhere. In the Summa Theologiæ it appears only in a few places in the first sixteen questions of the prima pars and not where it would be needed for most of the work analogy has been made to do, especially by English speaking writers, which is in the discussion of the sacraments in the tertia pars or the discussion of the Incarnation. Above all, therefore, the sacraments are not analogical in structure. This is because they are known and understood (literally, intellectus) through faith, even though the faith which discloses them is susceptible to reflective thought (intelligere). They are not worked out through reason, but the full truth of their being is disclosed in faith, through the intellect, that is through the speaking-together-with of reflective thinking.Footnote ⁴⁴

If the ground of the being for whom the guiding question is is disclosed through speaking, and that speaking which is both a speaking-alongside-and-together-with, and the speaking to the self which characterises the soul (Aristotle), then the being of this being can be fully disclosed without reference to God as highest being. Paradoxically to make God highest being, and so the ground of the being of beings as such is to strip human Dasein of its capacity for self-disclosure. I think St. Thomas never said differently – or rather he understood the difference between the constitutive modes of thoughtful self-disclosure of the human being's dwelling in truth, and the fulfilment of that truth in the life of faith. In this sense God ‘is’ beyond the self-disclosing speaking of being – or rather, as St. Thomas says, the being of God is fully known only to God, and to us only insofar as God chooses to reveal himself. St. Thomas’ theology is therefore and always a theology of revelation which requires reason to reflect on the revelation that has been given.

The reason that the sacraments do not fall under this is that the sacraments are disclosed through Christ (and Christ is himself above all a sacrament in this way), through the forms of beings that Christ chooses to disclose them in their everydayness – thus the Christ appears as a man amongst men,Footnote ⁴⁵ though fully divine; the Eucharist looks and behaves like bread, except that in faith we are given to know that it is fully and completely the body of Christ. Not through reason, but in faith alone. Moreover, the objectivity of these truths is not dependent on our faith, but on the infinite power of God.Footnote ⁴⁶

The equation God = Being is warranted only as a way of speaking in the order of faith, and of the reflective, intellective consideration of God's self-revealing. It is above all derived from scripture, as even Étienne Gilson affirmed.Footnote ⁴⁷ To make the (unwarranted) equation in the order of philosophy is, however, to make the move that Heidegger asserted ontotheology itself is – above all in the work of Hegel. Here the Incarnation becomes woven into the very structure of reason, so that it is the culmination of human Geist and at the same time entirely susceptible to reason's conditions. It destroys the freedom of the unbeliever not to believe – that is, to take Jesus as a mere man – in which very freedom is the possibility of our not being overwhelmed by God in his desire to redeem us.

Which brings us to the third of our questions, ‘third, what does it mean to say that the word being must not appear in any future theology?’. In Heidegger's enigmatic statement to the Zürich seminar of 1951, he was at pains to stress that “I believe that being can never be thought as the ground and essence of God, but that nevertheless the experience and manifestness of God, insofar as they meet with humanity, eventuate in the dimension of being, which in no way signifies that being might be regarded as a possible predicate for God”.Footnote ⁴⁸ This is exactly not the same as saying that the word being must not appear in any future theology, but rather, as Heidegger stresses, and I have already quoted, but which has always been overlooked in every consideration of this passage I have ever come across: ‘I think very modestly about being with regards to its use to think the essence of God’. Why is Heidegger modest with regard to this question? Surely because the being for whom God manifests himself amongst beings, as entering the realm of being to encounter humanity, is not God, but Heidegger himself and myself. Who would not be modest before God? How, above all for Christian men and women is this encountered to be understood, or rather with whom does it take place, except with that one who himself in all modesty enters the realm of being to save us, Jesus the Christ – before whom, who among us would not seek to be modest?

The foundation, the ground of being is to come into oneself as the being who asks the question, . To address Jesus the man with this question is to step reflectively into the request for an answer for the gift of faith, not a rational deduction of God as highest being. Who are you that you are? Who are you, O Lord, that you will save me? Or as Anselm knew this question: O Lord who promises me salvation, “Lord, you who give understanding to faith, grant that I may understand, as much as you see fit, that you are as we believe (you to be), and that you are what we believe (you to be).Footnote ⁴⁹ When asked as much as a question about who I am – who is it that believes – as a question about the extent to which God is disclosed and to be found in me – this then, is no prelude to a rational deduction of the existence of God, but truly, is my prayer to the non-metaphysical God who is my delight and my salvation.

The ground of the being of God is the being of being human – which leaves God free to be God with regard to us. Who would have known that God would seek to encounter us in the person – the being – of Christ? Thus the limit of theological thinking is described in the being of being human, but precisely irrupted in the order of faith by the promise that through Christ we might share in the divine life. The limit, insofar as it is known as a limit, can be known to be interrupted.
