It is quite funny to watch the liberals twisting and turning denying that allowing homosexual marriage may well lead to the legalization of polygamy. Of course it will! Once the present definition of "one man/one woman to the exclusion of all others" is replaced with "two people to the exclusion of all others", the question that very much deserves to be asked is: Why two people to the exclusion of all others? What is wrong with a threesome? Liberals cannot explain that. Our PM will say that polygamy is not in line with "Canadian values." But then if and when "Canadian values" change, we can change the definition again. Why not? Liberals cannot explain why not.
From a biblical perspective, polygamy must be condemned ("... from the beginning it was not so"). But is it not interesting that the Bible shows an abhorrence for homosexuality it nowhere shows for polygamy? Interestingly, in the time of the early church, there seems to have been an acquiescence to polygamy among converts. Men were not commanded to send away their 2nd and 3rd wives. Such men just could not serve as elders (1 Timothy 3:2 and Titus 1:6). Homosexuality, however, is roundly condemned (Romans 1:24ff).
