But we must first speak, I think, of the law of marriage, that we may afterwards discuss the forbidding of divorce. Some think that all marriage is sanctioned by God, because it is written, Whom God hath joined, let not man put asunder. (Matt. 19:6.) How then does the Apostle say, If the unbelieving depart, let him depart? (Mark 10:9, 1 Cor. 7:15.) Herein he shews that the marriage of all is not from God. For neither by God’s approval are Christians joined with Gentiles. Do not then put away thy wife, lest thou deny God to be the Author of thy union. For if others, much more oughtest thou to bear with and correct the behaviour of thy wife. And if she is sent away pregnant with children, it is a hard thing to shut out the parent and keep the pledge; so as to add to the parents’ disgrace the loss also of filial affection. Harder still if because of the mother thou drivest away the children also. Wouldest thou suffer in thy lifetime thy children to be under a step-father, or when the mother was alive to be under a step-mother? How dangerous to expose to error the tender age of a young wife. How wicked to desert in old age one, the flower of whose growth thou hast blighted. Suppose that being divorced she does not marry, this also ought to be displeasing to you, to whom though an adulterer, she keeps her troth. Suppose she marries, her necessity is thy crime, and that which thou supposest marriage, is adultery.
But to understand it morally. Having just before set forth that the kingdom of God is preached, and said that one tittle could not fall from the Law, He added, Whosoever putteth away his wife, &c. Christ is the husband; whomsoever then God has brought to His son, let not persecution sever, nor lust entice, nor philosophy spoil, nor heretics taint, nor Jew seduce. Adulterers are all such as desire to corrupt truth, faith, and wisdom.
