Christianity is no exception amid the general order of nature.  It follows that providential plan.  It grows from seed to flower.  Its beginnings were in a simple conception of ethical religion begotten in a heathen people through Moses.  In the womb of the nation it lay dormant till the time for quickening came.  Thenceforward it slowly assimilated the vital forces and nutritive elements of the organic life within which it grew, until the hour arrived when it burst the maternal womb, a perfect birth.  Christianity is a genuine historic evolution.

When we have said this, have we accounted for it?  To none save those who, in mastering the methods of a process of evolution, fancy that they have mastered its sources.  To none save those who, familiarizing themselves with the order of life, think that they have resolved its nature.  The wiser portion of mankind do not find in How a synonym for Whence.  We still ask whence?  When we see the issue of a long and complicated plan, we postulate a planning mind.  When we trace, through the sketches and studies in a studio, the gradual embodiment of a vision of loveliness, which at length looks down upon us in its perfect grace from the canvas on the wall, we cannot be persuaded out of our conviction that some artist has lived and labored in this studio, patiently evolving his great dream.  When we see a new-born child we do not think that we have learned its parentage in being told about its mother.  We want to know who fathered it into being.

What mind planned this process of a nation’s growth into a universal religion?  What artist dreamed this ethical and spiritual ideal?  Who begat this “holy thing” conceived in Israel and born of her at length in glorious beauty?  If Moses was the human parent of this marvellous child, who fathered the “essential Christ” in Moses?  Who is the real father of Jesus Christ?

Our only answer must be that given of old: 

When the fulness of the time was come God sent forth His son....  The true Light, which lighteth every man, was coming on into the world....  And the Word became flesh and dwelt among us (and we beheld His glory, the glory as of the only-begotten of the Father) full of grace and truth.

If this then be the true interpretation of the evolution of the Christ, we hold, in the doctrine of the Incarnation, the secret of all evolution.  We must read the story of every development in the light of the highest life of man, himself the highest life of nature.  Nature is in travail with an ideal which rose not in the molten suns, though perchance it did rise through them.

   The whole creation groaneth and travaileth in pain together until now. 
   For the earnest expectation of the creature waiteth for the
   manifestation of the sons of God.

Man is in travail with an ideal which rose not in the anthropoid apes, though it may have risen through them.  A finer, larger, nobler man is growing within the man that is.
