Chapter I.—Passages of Holy Scripture Compared.
You seem to me, O Theophila, to excel all in action and in speech, and to be second to none in wisdom. For there is no one who will find fault with your discourse, however contentious and contradictory he may be. Yet, while everything else seems rightly spoken, one thing, my friend, distresses and troubles me, considering that that wise and most spiritual man—I mean Paul—would not vainly refer to Christ and the Church the union of the first man and woman,  if the Scripture meant nothing higher than what is conveyed by the mere words and the history; for if we are to take the Scripture as a bare representation wholly referring to the union of man and woman, for what reason should the apostle, calling these things to remembrance, and guiding us, as I opine, into the way of the Spirit, allegorize the history of Adam and Eve as having a reference to Christ and the Church? For the passage in Genesis reads thus: "And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of man. Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh."  But the apostle considering this passage, by no means, as I said, intends to take it according to its mere natural sense, as referring to the union of man and woman, as you do; for you, explaining the passage in too natural a sense, laid down that the Spirit is speaking only of conception and births; that the bone taken from the bones was made another man, and that living creatures coming together swell like trees at the time of conception. But he, more spiritually referring the passage to Christ, thus teaches: "He that loveth his wife loveth himself. For no man ever yet hated his own flesh, but nourisheth and cherisheth it, even as the Lord the Church: for we are members of His body, of His flesh, and of His bones. For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the Church."
