Introduction
In his contemplative little book on grace, Charles Journet offers a word of warning about the proper mode of discourse when treating predestination. “If we forget,” Journet cautions, “that God is a God of love, if we speak [about predestination] without steeping [it] in the atmosphere of divine goodness that knocks at men's hearts, we may well say what would seem theologically—or rather, verbally, literally,—exact, but what would in fact be a deformation, misleading and false.”Footnote 1 Whatever concerns one may have about Journet's own contributions to the question of predestination, his advice corresponds perfectly with Thomas’ manner of proceeding when discussing predestination; namely, to remain steeped in the doctrine of the divine goodness. Thomas’ treatment of Christ's predestination is no exception to this practice.
Indeed, in a helpful summary statement that accentuates this point well, Daria Spezzano argues:
The entire graced journey of the human person to beatitude is properly understood as a particular manifestation of God's goodness, willed in the plan of divine wisdom for that individual. Thomas places it within the larger context of the communication of divine goodness, which is the ratio of creation and the effect of divine love.Footnote 2
The place of the incarnation within the plan of the manifestation of the divine goodness may be quite obvious on the surface, but perhaps, too, it is not always appreciated and integrated within treatments of the doctrine of predestination as much as it could be.Footnote 3
Authors have tended to reflect on the doctrine of Christ's predestination in two related, but distinguishable ways. On the one hand, Christ's predestination is taken to affirm the revelation of Christ's two natures, the divine nature, and the human nature predestined in the flesh to descend from David's lineage.Footnote 4 This account says little about the relation of the incarnation to predestination as such.Footnote 5 On the other hand, AugustineFootnote 6 views the Christological material as the realization of the divine plan to restore all things under Christ's headship.Footnote 7 In this light, the predestination of Christ is at one and the same time Christological and the highest instance of predestination,Footnote 8 which also has significant anti‐Pelagian connotations given that the Lord's incarnation was not brought about by any preceding merits.Footnote 9 This is especially evident in his work On the Predestination of the Saints, which Thomas frequently turns to in his teaching on Christ's predestination.
The central claim of this paper is that Thomas’ theology of the predestination of Christ is the locus where he ties together his theology of predestination—theology proper as discourse about God—with the realization of the eternal plan of predestination in the temporal order. This is so because Christ's predestination is not first to the created effect of filial adoption by grace, but to the diffusion of the divine goodness through the personal union of the two natures in the Word, from which the redemptive effects of eternal predestination are realized in time.Footnote 10 Indeed, it is not claiming too much to assert that Thomas recounts the totality of his doctrine of predestination only within his articulation of the predestination of Christ. As such, this material is a helpful resource for understanding his teaching on predestination, especially in light of how late it comes within his career and how complementary it is to his teaching earlier in the Summa.Footnote 11
This consideration focuses mostly, but not exclusively, on the Summa theologiae, and proceeds in three interrelated parts, moving from general principles to their temporal execution in Christ.
Part I: Predestination and the Ratio of Divine Goodness
Thomas’ sympathies in treating the predestination of Christ lie in the direction mapped out by St. Augustine in which the Christological aspects of Christ's predestination are presented in relation to their soteriological significance.Footnote 12 He opens his treatment of predestination in prima pars, question 23, by affirming that the rational creature is predestined by God—hardly a significant contribution. What is unique, however, about his affirmation of the rational creature's predestination by God is the ratio that he puts forward for the fittingness of this predestination—the very one that Journet urges to be kept in mind. What makes the predestination of the rational creature fitting is the two‐fold end to which the creature is directed by God. On the one hand, providence directs creatures to a proportionate natural end, which, Aquinas affirms, “created being can attain according to the power of its nature.”Footnote 13 On the other hand, there is the end of eternal life, “that consists in seeing God, which is above the nature of every creature.”Footnote 14 This end, Thomas teaches, “exceeds all proportion and faculty of the created nature.”Footnote 15 Thomas affirms the special grace filled divine direction of the creature to beatitude by using the passive verb “perducitur” and the participle “transmissa,” the creature is “led” and “carried” or “transmitted” by God to the end of eternal life. What makes this divine direction of the creature fitting is that the ratio of the ordering in Thomas’ words “pre‐exists in God…as the ratio of the order of all things towards an end.”Footnote 16 This makes it fitting for God to predestine precisely because, Thomas reasons, “the ratio in the mind of the doer of something to be done, is a kind of pre‐existence in him of the thing to be done.”Footnote 17
Therefore, the fittingness of the predestination of the rational creature by God is rooted in the preexistence of the reality of what the creature is predestined to in God himself. It is true that human nature has an obediential potency to be elevated in this fashion, but the question that Thomas raises is about God—whether it is fitting for him to predestine. Commenting on this, Reinhard Hütter explains that “Convenientia rejects these alternatives [whether the fittingness stems from one of either of the rational creature's two‐fold ends] by referring the matter to the mystery of God's goodness which is identical with God's justice as well as mercy, utterly unfathomable in the glorious simplicity of the divine perfection.”Footnote 18
Hütter's insight underscores a foundational element of the entire Christian doctrine of predestination, one that is often obfuscated by the complexity of the issue, namely, that the ratio of the movement or transmission of the rational creature to eternal life by God is the divine goodness itself.Footnote 19 This ratio is something that St. Thomas carries forward from his treatise on God to his treatment of the incarnation and the predestination of Christ.
In his work on the development of the doctrine of predestination in the thought of Thomas Aquinas, Michal Paluch notes a change in emphasis that takes place in Thomas’ articulation of predestination between the prima pars and the tertia pars of the Summa theologiae.Footnote 20 Given that several years and several thousand pages of material stand between the composition of question 23 of the prima pars and question 24 of the tertia pars, which considers the predestination of Christ, perhaps readers should not be surprised by some divergence in Thomas’ language.
Yet, in this case of tertia pars 24 on the predestination of Christ, Thomas refers the reader right back to the discussion of predestination that was put forward in prima pars 23, articles 1 and 2 as if he has the earlier material immediately before his eyes. “As is clear,” Thomas teaches, referring to quae in prima parte dicta sunt, “predestination, in its proper sense, is a certain Divine preordination from eternity of those things which are to be done in time by the grace of God.”Footnote 21 This statement is a very straightforward summary of the material in prima pars 23, but it is not reducible to any of the definitions that Thomas had set forth in the earlier material. Such as, for example, the “direction of a rational creature towards the end of life eternal” (ST, I, 23, a.1) or the “type of the ordering of some person towards eternal salvation, existing in the divine mind.” (ST, I, 23, a. 2).Footnote 22
The shift in emphasis to which Paluch draws attention to from prima pars 23 to tertia pars 24 stems from Thomas’ coupling of the eternal divine preordination that constitutes predestination in the divine mind with the working out in time of that preordination in the incarnation and gift of grace. This coupling is significant for a complete understanding of Thomas’ teaching on predestination. As Joseph Wawrykow notes, “There are in fact two aspects of, or ‘notes’ to, providence. Primarily, providence is the ordering by God of every creature to their ends: it is the plan that God has for their fulfillment. Secondarily, however, providence also involves the implementation of this plan that extends to all creatures. God orders; God implements the ordering, bringing every creature to the end set for it by God.”Footnote 23 The movement, therefore, from the treatment of predestination in terms of discourse about God to the implementation of the divine plan in Christ, indicates the reason for the shift in Thomas’ emphasis: he is speaking of the same divine reality in the tertia pars, but from the aspect of its implementation.
Part II: The Diffusive Nature of the Divine Goodness and the Fittingness of the Incarnation
This shift in emphasis from the eternal to the temporal aspects of predestination accentuates the recurring importance of the ratio of the divine goodness in Thomas’ account of predestination. This ratio creates a bond—solidified on predestination—between question 1 and question 24 of the tertia pars, and much of the material in‐between.Footnote 24
Thomas inaugurates both questions by inquiring of the fittingness of something pertaining to Christ, the incarnation in the case of the former question, and his predestination in the case of the latter.Footnote 25 It is interesting to note that the ratio of the fittingness of the incarnation is theological in nature, namely, that “the very nature of God is goodness.”Footnote 26 So Thomas seats the fittingness of the incarnation in the divine nature.Footnote 27 The fittingness of the incarnation is on account of the divine goodness, Aquinas reasons, because “it belongs to the essence of goodness to communicate itself to others.”Footnote 28 Furthermore, the incarnation is not simply a common mode of participation between God and creation. Rather, Thomas adds that the incarnation is the communication “of the highest good . . . in the highest manner.” The incarnation reaches this zenith, Thomas reasons, “by His so joining created nature to Himself that one Person is made up of these three—the Word, a soul and flesh.”Footnote 29
Thomas then develops a three‐fold “magis conveniens” and “convenientissium” for the incarnation of the Son rather than the Father or Holy Spirit.Footnote 30 He derives the second ratio for the special symmetry (congruentiae) of the incarnation of the Son and not the Father or the Holy Spirit, from the end of the hypostatic union, which, interestingly, he states to be “the fulfilling of predestination.”Footnote 31 The incarnation of the Son brings the plan of predestination to a more perfect fulfillment than would an incarnation of the Father or the Holy Spirit because the divine preordination is ordered to a heavenly inheritance that is bestowed Thomas observes, “only on sons.”Footnote 32 The incarnation as such is not fitting under the ratio of the divine goodness in a generic sense, but the ratio is further specified by the ordination of the saints to adoptive sonship—to a special conformity of the saints to the reality of the Word's eternal sonship. “That by Him,” Thomas argues, “Who is the natural Son, men should share this likeness of sonship by adoption.”Footnote 33
In his commentary on Romans, Thomas explicitly links God's plan to communicate the divine goodness with the Son's wish to communicate his sonship to the faithful. “For just as God willed to communicate his natural goodness to others by imparting to them a likeness of his goodness,” Thomas notes, “so that he is not only good but the author of good things, so too the Son of God willed to communicate to others conformity to his sonship, so that he would not be the only Son, but also the firstborn among sons.”Footnote 34
Furthermore, when considering whether, given the sinful creatures’ distance from God, it is fitting for God to adopt, Aquinas yet again appeals to the divine goodness: “God is infinitely good: for which reason He admits His creatures to a participation of good things,” and this, for the rational creature, “consists in the enjoyment of God, by which also God Himself is happy and rich in Himself.”Footnote 35
It is interesting to look at the question devoted to Christ's predestination under the light of this recurring theme: fittingness, each time he invokes it, is affirmed in relation to the divine goodness. When Thomas offers his tweaked definition of predestination as “a certain Divine preordination from eternity of those things which are to be done in time by the grace of God,” he immediately connects this definition with the superlative communication of the divine goodness that is realized in the hypostatic union: “Now, that man is God, and that God is man is something done in time by God through the grace of the union.”Footnote 36
Part III: Predestination as the Father's Gift to Christ—and to the Faithful through Christ
In the structure of the third part of the Summa theologiae Thomas locates his treatment of predestination within a two‐fold order. First, the question on Christ's predestination is included in a group of eleven questions commencing with question 16 which, in Thomas’ words, “consider the consequences of the union.”Footnote 37 Within this grouping of topics that follow upon the union, Thomas identifies a subgrouping of questions on Christ's subjection, prayer, priesthood, adoption, and predestination. This group of topics, Thomas explains, pertain to “such things as belong to Christ in relation to the Father.” So, Christ's predestination is (a) a consequence of the union and (b) something that belongs to Christ in relation to the Father.
Thus Thomas views the hypostatic union as the realization of the diffusive nature of the divine goodness, which in turn corresponds to the fittingness of the predestination of Christ, as it accomplishes in time the divine preordination of the rational creature to eternal life.
There is a kind of connecting member that is provided here for the overall plan of the Summa and Christ's place therein. “It cannot be said,” Thomas argues in defense of the fittingness of the predestination of Christ,
that God has not from eternity pre‐ordained to do this in time: since it would follow that something would come anew into the Divine Mind. And we must admit that the union itself of natures in the Person of Christ falls under the eternal predestination of God. For this reason do we say that Christ was predestined.Footnote 38
What is to be made, then, of the Thomas’ clear and consistent declaration that predestination properly understood is a theological reality in the strong sense of the word theological—something whose ratio is in the goodness of the divine essence and not in the creature? Thomas identifies his treatment of the predestination of Christ as a consequence of the hypostatic union, and further as an instance of Christ's relation to the Father and not to humanity. To what degree, then, does the properly theological nature of predestination allow for Christological and temporal articulations?
To explain this difficulty, Thomas argues that “two things may be considered in predestination. One on the part of eternal predestination itself: and in this respect it implies a certain antecedence in regard to that which comes under predestination.”Footnote 39 This is the properly theological domain of predestination. From another perspective, however, Thomas explains, “predestination may be considered as regards its temporal effect, which is some gratuitous gift of God.”Footnote 40 How then does this pertain to Christ's relation to the Father and not the Father's or Christ's relation to humanity?
Thomas supports this point by underscoring the link between Christological orthodoxy, on the one hand, and the eternal plan for the predestination of Christ, on the other: from both the eternal and the temporal point of view “we must say that predestination is ascribed to Christ by reason of his human nature alone: for human nature was not always united to the Word; and by grace bestowed on it was it united in Person to the Son of God.”Footnote 41 The hypostatic union is a singular, gratuitous effect realized in time of the Father's eternal plan.
Given the unmerited gratuity of the predestination of Christ's human nature to the grace of personal union with the Word, to what degree can the incarnation as such be said to contribute anything whatsoever to the realization of the plan of salvation in history? Thomas readily concedes that “on the part of the act of predestination,” on the side of its eternity in God, “Christ's predestination cannot be said to be the exemplar of ours: for in the same way and by the same eternal act God predestined us and Christ.”Footnote 42
However, Christ's predestination, as an unmerited gift from the Father, can be considered in relation to ours from the perspective of its term or ad quem point of reference. “In respect of the good to which we are predestined,” Thomas notes that Christ, “was predestined to be the natural Son of God, whereas we are predestined to the adoption of sons, which is a participated likeness of natural sonship.”Footnote 43 The perfection of filiation communicated to the creature in predestination resides in the natural sonship of the incarnate Word.Footnote 44
Furthermore, Thomas speaks of the “manner of obtaining this good” to which predestination is ordered, “—that is, by grace.” So how does God move the rational creature to the good of participation in eternal life—how is the divine goodness diffused? Christ's predestination to natural sonship—personal union—exemplifies filial adoption because “human nature in Him, without any antecedent merits, was united to the Son of God: and of the fullness of His grace we all have received.”Footnote 45 So Christ's predestination does relate to the predestination of the saints as possessing the perfection of natural sonship to which they are ordered to participate, and the means to this participation, namely, his own fullness of grace.
Affirming that the exemplar realities of predestination reside in Christ's predestination does not clarify the manner, if there be one, of any causation that can be attributed to Christ. In fact, as Thomas recognizes in an objection, it seems impossible, given his general teaching on predestination as an eternal reality in God, that Christ's predestination exercises any soteriological influence on the faithful. “For that which is eternal has no cause,” Thomas affirms in an objection, “But our predestination is eternal. Therefore Christ's predestination is not the cause of ours.”Footnote 46
To address the causal relation of Christ's predestination to that of the saints, Thomas again turns to the distinction between the act and the term of predestination. In so doing he gives explicit articulation to his affirmation in the prima pars of the role that secondary causes have within the unfolding of the divine plan. By the act of predestination Christ's cannot be the cause of ours, Thomas teaches, “because by one and the same act God predestined both Christ and us.”Footnote 47 This seems to negate any causal agency on the part of Christ in relation to our reception of grace. Yet Thomas argues that “Christ's predestination is the cause of ours: for God, by predestinating from eternity, so decreed our salvation, that it should be achieved through Jesus Christ.”Footnote 48 Here Thomas makes explicit how secondary causes are related to the eternal plan of predestination: “eternal predestination covers not only that which is to be accomplished in time, but also the mode and order in which it is to be accomplished in time.”Footnote 49
These reflections raise the question of a putative equivocation to which Thomas is especially sensitive in his commentary on Lombard's Sentences. In what sense can predestination as an eternal decree, Christ's predestination to natural sonship, and the predestination of the saints be treated under any common notion? “In predestination there are two things,” Thomas adds in his commentary on the Sentences, “one eternal, namely the very operation of God, and another that is temporal, namely the effect of predestination.”Footnote 50
From the formally theological perspective, no created agency, not even Christ's, causes God's eternal decree. “Therefore our predestination as that to which is eternal in itself, does not have a cause but,” Thomas quickly adds, “as to the effect it can have a cause, namely in so far as its effect is produced by means of some created cause.”Footnote 51
This establishes a connection between Christ's predestination and that of the saints: “according to this,” Thomas affirms without hesitation, “the cause of our predestination is the predestination of Christ. Efficiently in so far as he is the mediator of our salvation; and formally in so far as we are predestined children of God in his image; and finally, in so far as our salvation overflows from his glory.”Footnote 52
The believer is, furthermore, granted a participation in Christ's fullness through the providential establishment of the causal efficacy of the sacraments. Because “divine providence” provides for each thing, Aquinas notes, “according to the mode of its condition. Divine wisdom, therefore, fittingly provides man with the means of salvation, in the shape of corporeal and sensible signs that are called sacraments.”Footnote 53 This does not mean that the sacraments of the Church somehow constitute a second or secondary plan of salvation within the plan of predestination. Rather, Aquinas explains, “Christ's passion is, so to say, applied to man through the sacraments.”Footnote 54
Conclusion
To return again to the work of Daria Spezzano, it is worth quoting at length a helpful summary that she makes of many of these themes:
As the creature is conformed to the Word by wisdom and in the intellect, so it is also conformed to the Word insofar as it is through the Word that God carries out the divine plan of wisdom for the universe and for each individual creature, manifesting his glory. The predestination of the elect to beatitude, toward which they move by participation in the Word and Love through wisdom‐perfected charity, fully reveals the splendor of God's glory—the knowing and praise of the divine goodness—in the divine plan of providence.Footnote 55
Thomas’ doctrine of the predestination of Christ provides light and clarity to his general treatment, especially concerning how the eternal reality of predestination unfolds in time and how the incarnation realizes the divine plan under the ratio of the goodness of God. Thomas accomplishes an elusive theological task with his doctrine of the predestination of Christ: namely, the articulation of the unfolding of the divine plan in time under the ratio of the divine goodness, while openly affirming the created means used to confer the temporal effects of the divine plan, without ever abandoning a gratuitous and God‐centered account of predestination.
