Ignatius to the Ephesians XVIII

Let my spirit be counted as nothing for the sake of the cross, which is a stumbling-block to those that do not believe, but to us salvation and life eternal. “Where is the wise man? where the disputer?” Where is the boasting of those who are styled prudent? For our God, Jesus Christ, was, according to the appointment of God, conceived in the womb by Mary, of the seed of David, but by the Holy Ghost. He was born and baptized, that by His passion He might purify the water.
