mP, that's off-topic, but I feel I owe you an answer. You seem to be stuck on slavery, blaming the Bible writers for condoning it. Keep in mind that none of the other religions opposed slavery. I think it is unfair that you single out Christians.
For one, ancient economies were dependent on slavery. Trying to change that would make one very unpopular. Secondly, war was commonplace and the victor usually took slaves from those he subjugated. This was a fact of life.
Jesus made it clear how he viewed things. You must love God with your whole heart and your neighbour as yourself. You must even love your enemies and do good to those persecuting you. One should therefore not see his followers as “reformers.” Rather one should view them as regulators. They adapted themselves to their surroundings in order to survive, at the same time trying to stay true to their faith. Yes, they even regulated those that were slaves. They were not interested in transforming the world or rewriting history, but awaited a “city having real foundations and the builder and maker of it is God” (Hebr. 11:10, 39, 40). .
How long would slavery be around for? Till 200-300 years ago, just the other day. If you watch the news, you’ll see that some forms of it is still with us today. But then slavery was the order of the day. To understand the position Christians found themselves in, one could utilize form criticism, developed by Hermann Gunkel. He coined the phrase Sitz im Leben des Volkes, creating a critical methodology of form criticism (Formgeschichte), by examining the genres used in the biblical text to identify the Sitz im Leben (setting in life) that produced the text. His approach is based on the assumption that each genre is organically associated with a particular social and historical situation. Form criticism is in fact the separation of genre history from text history, and the relationship of transmission history to the history of religions and culture. See The Hebrew Bible and Its Modern Interpreters, pp. 136, 149.
One cannot dress the Bible in 21st century garb. By being biased or ignoring historical or social realities, one tears the apostle out of his age, tears the gospel out of history and blocks off Scripture from the light of modern research.
