83:6.3

The Chaldean tribes recognized the right of a wife to impose a premarital pledge upon her spouse not to take a second wife or concubine; both the Greeks and the Romans favored monogamous marriage. Ancestor worship has always fostered monogamy, as has the Christian error of regarding marriage as a sacrament. Even the elevation of the standard of living has consistently militated against plural wives. By the time of Michael’s advent on Urantia practically all of the civilized world had attained the level of theoretical monogamy. But this passive monogamy did not mean that mankind had become habituated to the practice of real pair marriage.
