The Biblical View Of Divorce - WCF 24.5-24.6

24.5 Adultery or fornication, committed after a contract, being detected before marriage, giveth just occasion to the innocent party to dissolve that contract. In the case of adultery after marriage, it is lawful for the innocent party to sue out a divorce, and after the divorce to marry another, as if the offending party were dead.

³¹“Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ ³²But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery. (Matt. 5:31-32)

25.6 Although the corruption of man be such as is apt to study arguments, unduly to put asunder those whom God hath joined together in marriage; yet nothing but adultery, or such willful desertion as can no way be remedied by the church or civil magistrate, is cause sufficient of dissolving the bond of marriage; wherein a public and orderly course of proceeding is to be observed; and the persons concerned in it, not left to their own wills and discretion in their own case.

⁸He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so. ⁹And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.” (Matt. 19:8-9)
