Yet as guidance toward this he has already said a few words earlier: Christ nourishes and warms the Church, and we are of His flesh and of His bones. After this it is not difficult to carry the correspondence further. In the words expressing the essence and indissolubility of marriage, one may also see the expression of the mystical union of Christ the Lord with the Church.
In the Incarnation, the Son of God as it were left His heavenly Father, though without being separated from Him. He entered into mystical union with redeemed humanity, the Church, which is likewise from His rib and together with Him forms one.
Chrysostom does indicate a great mystery also in the marital union. Yet for him too the true mystery lies in the Lord's condescension and His union with the Church. He says: "Truly this is a mystery, that a man leaves the one who brought him forth, begot him, and raised him, and the one who conceived him, suffered for him, and bore him in travail.
"He leaves those who bestowed so many benefits upon him, and to whom he was accustomed. He is joined to one whom he had not previously seen, who has nothing in common with him, and he prefers her to everything. Truly this is a mystery.
"The parents do not grieve. On the contrary, they grieve when this does not happen. As a sign of joy, they do not spare money and expenses. Truly this is a great mystery, containing within itself some hidden wisdom."
But Chrysostom said this after he had already indicated in these words the mystery of the union of Christ the Lord with the Church. "I speak," says the Apostle, "with respect to Christ," because He also, having left the Father, came down and came to the bride and became one spirit with her, and she with Him. For "he who is joined to the Lord is one spirit with the Lord" (1 Cor 6:17).
Theodoret writes the same: "Christ Himself, having left the Father above, was joined to the Church. But He left Him according to the concept of His becoming man, because, as God, He is not separated from God, since He Himself also has an uncircumscribed nature." In this lies the mystery.
Blessed Jerome explains this truth more fully: "Not the whole account of Adam and Eve written in Genesis can conveniently be referred to Christ and the Church, as some think. Only what is said in the present passage can be so referred, namely: 'For this reason a man shall leave his father and mother and cleave to his wife, and the two shall be one flesh.'
"The first man, Adam, as the first prophet, foretold this concerning Christ and the Church: that our Lord and Savior would leave His Father, God, and His mother, the heavenly Jerusalem. He would come to earth for the sake of His body, the Church, and form her from His rib. For this reason the Word became flesh.
"And since not all mysteries are equal, but one mystery is greater and another smaller, he now says: 'This mystery is great.' Showing at the same time a sign of his humility, he adds: 'but I speak with respect to Christ and the Church.'
"Gregory Nazianzen, a most eloquent man and very learned in Scripture, when we discussed this passage with him, said more than once: 'See what the mystical depth of that little passage is, it seems in Genesis. When the Apostle interprets it with respect to Christ and the Church, he does not assert that he has explained it as the dignity of the testimony requires.
"'Rather, he spoke as though saying: I know that this passage is full of ineffable mysteries and requires from its interpreter a divine heart. But I, according to the smallness of my understanding, think that it should be understood with respect to Christ and the Church.
"'This is not because anything is greater than Christ and the Church, but because it is very difficult to explain everything said about Adam and Eve with respect to Christ and the Church.'"
