You demanded an answer from me and I gave it to you in the voice of Jesus Christ himself.
Now I demand an answer from you. Would there have been a war if the southern patricians has freed their slaves?
“You demanded an answer from me and I gave it to you in the voice of Jesus Christ himself.”
No you didn’t. What you provided are a couple of out of context verses from Matthew where Jesus was debating Pharisees. Their discussion involved marriage and rendering what is owed to Caesar. There is no mention of slavery in that chapter.
Matthew’s Gospel does mention slavery but not from where you quoted.
Matthew 18:23-35 speaks of a slave who is punished by his master for being unforgiving.
Matthew 21:33-41 features a group of slaves who are killed and no one objects.
Matthew (10:24) tells us that “slaves are not above their masters” .
Matthew 24:46: “Blessed is that slave whom his master will find at work when he arrives”.
Jesus didn’t take the opportunity to condemn slavery in any of those Matthew verses. Jesus spoke of slaves as a fact of life. People are owned by other people. But you should keep looking for that chapter and verse where Jesus discusses slavery and calls it a sin.
