"Oh, what a ridiculous thing, that the one true God, the high Majesty, should be made man; that here they should be joined, man and his Maker, in one Person. Reason opposes this with all its might.
Here, then, those wise thoughts with which our reason soars up towards heaven to seek our God in His own Majesty, and to probe out how He reigns there on high, are taken from us. The goal is fixed elsewhere, so that I should run from all the corners of the world to Bethlehem, to that stable and that manger where the babe lies, or to the Virgin's lap. Yes, that subdues the reason.
Do not search what is too high for thee. But here it comes down before my eyes, so that I can see the babe there in His mother's lap. There lies a human being who was born like any other child, and lives like any other child, and shows no other nature, manner, and work than any other human being, so that no heart could guess that the creature is the Creator. Where, then, are all the wise men? Who would ever have conceived this or thought it out? Reason must bow, and must confess her blindness in that she wants to climb to heaven to fathom the Divine, while she cannot see what lies before her eyes."
Martin Luther, sermons from the year 1533
