@Frank Apisa,
He certainly did though. Wives were servants. He was very outspoken about the stoning of Mary by people who weren't authoritative enough to even do so. I don't think there were slaves. The Hebrews were "free" so to speak, but it was Roman rule, they were, being nice to Hebrews but Hebrews weren't totally equal, they were like, Native Americans. I think slavery was outlawed at the time; there weren't any gladiators either (actually I'm probably wrong about that, but considering God later saves gladiators who are Christians he is "speaking out" then. Why are Christians "becoming equal" "with powers" with Greek masters if he isn't against slavery? The good Christian cannot be eaten in the gladiator pit, nor consumed by flame; gladiators who are less than slaves. There he has freed a slave because that's what it took to free a slave, often.)
Greek slavery wasn't the same evil, though; probably an 'invalid point' but Greek slavery was different, and it wasn't as evil as modern slavery. A Greek slave could become free, and could often learn.
I think that Jesus wasn't speaking out against Institutions but God Law too, a point; he wasn't a human man. It was really beneath him to comment on man's institutions but those of God, His; unlike book "Zealot" eye roll .
He is spreading his message of peace, where it really seems to suggest he is against slavery too then, or war.
