Christianity, by those doctrinal aspects that we have just emphasized as well as by others, brought something absolutely new into the world. Its conc… - Henri de Lubac

In a non-transcendent society, the reduction of man to his "social relationships" will work inevitably to the prejudice of his personal interiority, and will beget a tyranny of some kind, however novel. Moreover, have we not already the right to think, short as is our experience of this sort of thing, that it provides our analysis with its first confirmation? When Marx's followers eventually become aware of this, they will have no longer any inclination to extol that "total revolution" that they suppose themselves to have achieved in human intelligence before implanting it in society. They will have no longer any inclination to sing of their deliverance from "metaphysical agony" and from the "obsession of God". They will have to return to "those accursed eternal questions", as Dostoievski called them.

The effort of the intelligence can aim only at better understanding reflexively the given of faith.[…] All minds, however, do not experience equally the need for such an effort. It is nonetheless very often necessary for them, on the level where their natural speculation usually moves, for dogmas to be given a certain coherent view, more systematized than the teaching of the Church, which renders these dogmas more assimilable to them and which prevents ever-possible deviations. Whence the permanent usefulness of theories that are constructed, through the arrangement of concepts, within common sense, starting with uncriticized representations. Their intellectual value can be weak. To admit them is not, however, pure pragmatism, since they are useful, not for any end whatsoever, but for the maintenance of a truth.… [W]e call to mind one case of this kind by citing the theory of the scientia media: it remains a necessary support for those who need to conceive of the relations between grace and human freedom as an organized system and who could not otherwise preserve the idea of freedom.… [Footnote:] Let us observe, however, that such theories, while they serve to maintain a truth on which attention is fixed, generally thereby compromise a complementary truth, which it is sometimes no less important to hold. We know well enough the weak point in Molinism.

The most unbending thoughts are the most vulnerable to change.
