You have no idea what you’re talking about.
That’s why you don’t source out your scripture for it. You can find pockets of progressive thought in the Bible,
“Slaves, be subject to your masters with all reverence, not only to those who are good and equitable but also to those who are perverse. For whenever anyone bears the pain of unjust suffering because of consciousness of God, that is a grace. But what credit is there if you are patient when beaten for doing wrong? But if you are patient when you suffer for doing what is good, this is a grace before God. For to this you have been called, because Christ also suffered
* for you, leaving you an example that you should follow in his footsteps.”
“Slaves, obey your human masters in everything, not only when being watched, as currying favor, but in simplicity of heart, fearing the Lord.”
“Slaves are to be under the control of their masters in all respects, giving them satisfaction, not talking back to them stealing from them, but exhibiting complete good faith, so as to adorn the doctrine of God our savior in every way.”
“Those who are under the yoke of slavery must regard their masters as worthy of full respect, so that the name of God and our teaching may not suffer abuse. Those whose masters are believers must not take advantage of them because they are brothers but must give better service because those who will profit from their work are believers and are beloved”
The Bible is overwhelming pro slavery. Majority of the passages speaking about slavery are telling slaves to obey. Your proof for it not being pro slavery is saying, “slaves earn your freedom” or a story about an apostle returning a slave to his master. That isn’t very convincing stuff bud.
