One of the pastoral problems which loom very large in these days is that of the Catholics who, having entered upon a marriage which the Church cannot recognise as such, then find themselves tortured in mind by their consequent separation from the sacramental life of the Church, and long to return to it but see no way of doing so. What is to be done for them? How are they to be advised?

It is as useless as it is heartless to say simply that they have only themselves to blame: that they sinned in contracting a marriage which is no marriage at all, and that the Church will receive them back when, and only when, they renounce it. In practice this is harmful, since it may well drive them completely and finally away from the Church. In theory it is bad theology, because it simplifies what is in reality complex, and refuses to face all the facts of a human situation. Ethics is not an exact science, precisely because its business is with the complexities and untidiness of human action in the concrete; and indeed the ultimate ethical judgment, as to what A is to do here and now, is not a question of science merely but of art, the art of prudence. We might well recall here some wise words of M. Maritain: ‘Some people imagine that morality measures our actions, not in the light of the just human ends which they ought to be aiming at in the given circumstances, but by a forest of abstract formulae which life must copy like a book. ... In reality the principles of morals are not theorems or idols: they are the supreme rules governing a concrete activity the aim of which is something to be done in certain definite circumstances, and governing it through more proximate rules and above all through the rules, which are never set down in advance, of the virtue of prudence. . . . They do not seek to devour human life; they are there to build it up.
