1 Corinthians 7:11
But and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife. But and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife.
A wife who leaves her husband is to stay unmarried or be reconciled to him, and a husband is forbidden to dismiss his wife. Separation does not dissolve the marriage bond, and a divorce in itself does not set either husband or wife free to marry another. Putting asunder a husband and wife is a grave act that must have Scriptural warrant, with adultery held as the only lawful ground for separation.
Where a wife loves her husband nothing in the word requires her to separate from him, and she should continue with him. A husband fulfills the prohibition against putting away his wife by loving her, doing all in his power to help her and to keep her with him, and refusing to send her away even when she is unworthy and unkind and bent on having her own way. When the wife goes away while the husband has not left her, the fault is not his.
If the wife herself departs, puts away her husband, secures a divorce contrary to earnest counsel, and marries another man, the husband who did not put her away is free to marry again in the Lord, and that new union is lawful and is not to be broken up. A later divorce does not open the way to a new marriage for a husband who had already forsaken his wife and formed another attachment while still legally married, since his own course helped to produce the divorce. A second marriage made with parental consent and with full knowledge, in which the woman loves the man and knowingly accepts him with his physical defect, can be in the order of God to bring to both a richer Christian experience and to build each up where lacking, and once marriage vows are pledged they cannot be annulled, so that to break them would be far from right.
