For our fifth very radical change we note how Jesus changed the Old Testament patriarchal laws of marriage and divorce. A Jewish man could have several wives, add concubines to his harem, and divorce any of these when he chose. Women are rightly horrified by the law of Moses. But there was no provision for a woman to divorce a Jewish man under any circumstances. Jesus ended that gross imbalance against women.
Women have the same duties and rights as men.
Like other rabbis Paul had begun with a male chauvinist view of women. But when he was converted, and slowly seen the implications of Jesus' attitude to marriage and divorce, he gave the Corinthians an astonishing tenfold mutuality between women and men in marriage. The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the unbelieving husband is made holy through his wife, and the unbelieving wife is made holy through her husband. The idea that a wife could make her husband's children holy has undermined the very basis of Old Testament patriarchy.
