“At the source of its developments an operation was called for, transcendent in order, to graft the person of a God onto the human cosmos, under conditions that are mysterious but physically governed . . . Et Verbum caro factum est. This was the Incarnation. From this first and fundamental contact between God and the human race—which means in virtue of the penetration of the Divine into our nature—a new life was born: an unlooked for magnification and “obediental” extension of our natural capabilities— grace . . . Grace is the unique sap that starts from the same trunk and rises up into the branches, it is the blood that courses through the veins under the impulse of one and the same Heart, the nervous current that is transmitted through the limbs at the dictate of one and the same Head: and that radiant Head, that mighty Heart, that fruitful Stock, must inevitably be Christ. . .”
