I'm going to say that the Bible is a fusion of Eastern and Western civilizations. There is a pretty clear path from the ancient Fertile Crescent through Israel to Greece and Rome. All these had their impact on the evolution of the Bible, not the other way round. To it's credit, Christian Europe's feudalism was the first major culture that was NOT based on slavery. The serfs were not much better off but they were not slaves either. In this country Quakers were in the vanguard of the Abolitionists but Southern Baptists went the opposite way:2. But….I’m gonna say that, aside from being responsible for Western Civilization, a whole bunch of super ideas came by way of the Bible. And by that, I mean largely in opposition to every other religion of antiquity. Brand, spanking new ideas that came from no other philosophy!
Struggling to gain a foothold in the South, after the American Revolution, the next generation of Southern Baptist preachers accommodated themselves to the leadership of Southern society. Rather than challenging the gentry on slavery and urging manumission (as did the Quakers and Methodists), they began to interpret the Bible as supporting the practice of slavery and encouraged good paternalistic practices by slaveholders. They preached to slaves to accept their places and obey their masters. In the two decades after the Revolution during the Second Great Awakening, Baptist preachers abandoned their pleas that slaves be manumitted.[24]
Europeans did indeed have slavery co-existing with feudalism; the Italian city-states for one had plenty of them working the farms and clothmaking factories and rowing the galleys. Thousands of wills survive of merchants lisitng their slaves as assets and how they wished to dispose of them throughout the Renaissance era. Spanish, Dutch, French, and English colonies were full of slaves. right up to the 19th century.
