The truth of history lies simultaneously in the substratum of created existence (since all beings are the willed realizations of God's love); in the fulfillment of the future of history (since God's love, in His will and its expressions - namely, created existence - is identifiable with the final communion of creation with the life of God); and in the incarnate Christ (since on God's part the personification of this loving will is the incarnate Christ). Whereby Christ becomes the "principle" and "end" of all things, the One who not only moves history from within its own unfolding but who also moves existence even from within the multiplicity of created things, toward the true being which is true life and true communion.
