The Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing.
Martin LutherThe Son of God did not want to be seen and found in heaven. Therefore he descended from heaven into this humility and came to us in our flesh, laid himself into the womb of his mother and into the manger and went on to the cross. This was the ladder that he placed on earth so that we might ascend to God on it. This is the way you must take.
Martin Luther
