c. 246–248 · Origen, Commentary on the Gospel of Matthew 14.16
But they did not perceive in what way He answered blamelessly and wisely, in the first place, rejecting the opinion that a wife was to be put away for every cause, and, in the second place, giving answer to the question about the bill of divorcement; for He saw that not every cause is a reasonable ground for the dissolution of marriage, and that the husband must dwell with the wife as the weaker vessel, giving honour, and bearing her burdens in sins; and by what is written in Genesis, He puts to shame the Pharisees who boasted in the Scriptures of Moses, by saying, “Have ye not read that He who created them from the beginning made them male and female,” etc., and, subjoining to these words, because of the saying, “And the twain shall become one flesh,” teaching in harmony with one flesh, namely, “So that they are no more twain, but one flesh.” And, as tending to convince them that they should not put away their wife for every cause, is it said, “What God hath joined together, let not man put asunder.”
