I'm pretty sure monogamy isn't an exclusivity to Christianity, Pagans already practiced it according to some sources I read.
As anyone knows with just a whiff of historical knowledge, the Romans practiced monogamy and so did the Greeks. Mainländer, you know this! Why else do you think Julius Caesar was married four times in succession or Socrates kept to his shrew wife, Xantippa?
I'd say monogamy is typical of Indo-European societies, in other words, it has pagan roots.
At the same time, monogamy is NOT Biblical. The Hebrews of the Old Testament practiced polygony. Abraham had two wives, remember, and King Solomon kept a harem of several hundred women who were married to him. In fact, the Hebrew world of the Bible has more in common with Islam in terms of marriage custom than Greaco-Roman antiquity or Christendom.
Without the Jews, no Christianity. Without Christianity, no enforced monogamy. Without enforced monogamy, most here would never have been born.
Incorrect. It was due to the heathen environment in which Christanity developed that it came to enforce monogamy wherever it went. Jewry of the classical age had nothing to do with it and the Hebrews of earlier times were full blown polygynists.
Like everything else that is great about Christendom, monogamy came from Greaco-Roman paganism, and not from the Hebrew desert of shrieking fanatics.
