Origen

“ After this we will discuss the saying of the Pharisees which they said to Jesus, “Why then did Moses command to give a bill of divorcement and put her away?” [1] And with good reason we will bring forward for this purpose the passage from Deuteronomy concerning the bill of divorcement, which is as follows: “But if a man taketh a wife and cohabit with her, and it shall be, if she do not find favour in his sight because he hath found in her a thing unseemly,” etc., down to the words, “and ye shall not pollute the land which the Lord your God giveth you for an inheritance.” ”

“ But if any one ascends to the Gospel of Christ Jesus which teaches that the law is spiritual, he will seek also the spiritual understanding of this law. And he who wishes to interpret these things figuratively will say that, just as it was said by Paul confident in the grace which he had, “A wife is bound for so long time as her husband liveth, but if the husband be dead she is free to be married to whom she will, only in the Lord ”

“ And he will say that, unless one law is spiritual and another is not such, this is a law, and this is spiritual, and its spiritual significance ought to be investigated.
