Not quite:<quoted text>lol
They did proclaim, many times, that man should not slave for man. In 1 Cor 7:21-23, Paul said that a slave should seize the opportunity of freedom and stop being slaves of men.
Anybody can Google the bible, ya know?
"21 Were you a slave when you were called? Don’t let it trouble you—although if you can gain your freedom, do so. 22 For the one who was a slave when called to faith in the Lord is the Lord’s freed person; similarly, the one who was free when called is Christ’s slave. 23 You were bought at a price; do not become slaves of human beings."
This verse applies to Christians. It says if you are a slave and can obtain your freedom do so. It also says that Christians should not become slaves.
That is rather weak. Let's see what New Testament verses support slavery:
And I messed up, it was Paul that sent a slave back to his master, not Peter. He suggested that the master free the slave but he did not tell the owner that slavery was evil.
If anything the New Testament treated slavery as a necessary evil and early Christians saw slaves as a ready market for converts.
