[Abigail Adams]

Ephesians 6:5 says "Slaves, obey your earthly masters with respect and fear, and with sincerity of heart, just as you would obey Christ."

Does that mean that Paul is endorsing slavery?

[Prophet in the wilderness]

" Does that mean that Paul is endorsing slavery? "

Nope.

I do not believe that he or Christianity endorsed slavery, however, that was the times and age that he was living in, and even today we still have slavery in parts of the world.
I think Paul was trying to tell the slaves not to make matters worse and try to make a bad situation work out for the good.

Paul was concentrating on the higher things knowing, intuitively, that as Garce builds upon nature, the natural consequence of Christianity would be the gradual elimination of slavery.

Love, eventually, conquers all; and in Christ, behold, all things are made new; even the master - slave relationship (which was well-established prior to the Incarnation)

[Salvation]

No, I don't think Paul was endorsing slavery, but rather addressing an issue of the time. Amazing that it is relevant to some countries in the world, even today, isn't it?
