Philemon 1:16

Not now as a servant,— The word Δουλον should have been translated a slave. Slaves were then bought and sold, like cattle, in the market; and the descendants of such slaves were born slaves: they did not receive wages, nor could they at their pleasure hire themselves to other masters, but were looked upon as their master's goods and possessions. Christianity, as we have often observed, does not alter men's civil obligations or privileges; but it should be observed, that the buying and selling men for slaves is quite another matter, and one which much concerns those who are engaged in it very seriously to consider: and it is with great pleasure, that on this occasion I refer to Mr. Granville Sharpe's humane and benevolent treatise on the subject, entitled, "A Representation of the Injustice and dangerous Tendency of tolerating Slavery."
