[T]hough not being absolutely the same as ours, the difficulties for a Saint Peter or a Saint Paul in believing were no less strong. Nor were those o… - Henri de Lubac

In the One there is no solitariness, but fruitfulness of life and warmth of presence.[…] In the all-sufficient Being there is no selfishness but the exchange of a perfect Gift. The created mind, though so faint a copy of him who is, is none the less a reproduction in some sort of his structure—ad imaginem fecit eum—and practiced eyes can discern the stamp of the creating Trinity. There is no solitary person: each one in his very being receives of all, of his very being must give back to all.[…] Thus it can also be said, to exalt its inner richness and to make clear its character as an end, which all others must acknowledge, that "a person is a whole world", but it must also be added at once that this "world" presupposes others with which it makes up one world only.

Flight, Escape: that in fact was Plato's dictum regarding the soul that acknowledges in itself a principle superior to the world. Plotinus, in his turn, recommended to his disciple the "flight of the alone to the Alone", and then Porphyry expiates on the setting free and the withdrawal of the soul. The same terms may be encountered in the religious philosophies of India.[…] With the Buddhist, too, it is the same act of negation, whether he denies the existence of the world or believes in the reality of his present wretchedness; and he who practises charity to a degree that sometimes reaches the sublime in the last resort relinquishes even that. Asanga, the great mystical doctor of the Mahâyâna, when he starts to map out the path of his bodhisattva's ascent from "world" to "world" until he reaches the very highest state, which is that of Nirvâna, as a matter of course describes it as a whole series of evasions: niryàna; so much so that it has been said that Buddhism's only God is Escape.

The Gospel is full of paradoxes, by which the mind is at first troubled. The Savior teaches with great simplicity, yet he says also, "Blessed is he that shall not be scandalized in me." And it is a question, at least, whether all substantial spiritual doctrine must not of necessity take a paradoxical form.
