[Q
And the Bible does not condone slavery, nor does it tolerate it. Also, you are mistaking what the word slavery, in the Bible, actually meant. It was referring to indentured servitude. The Bible also gave guidelines on how to treat "slaves" The Bible also condemns what we know as modern slavery. People used to get the death penalty for practicing it. So, you really need to educate yourself. Your ignorance offends every thinking person on here.
What the New Testament says about slavery
The purpose of the series of essays on slavery was to point out that there have been some examples of positive changes in morality since biblical times. When the authors of the Hebrew and Christian Scriptures (a.k.a. Old and New Testaments) were alive, slavery was a perfectly normal and expected social institution.
Matthew 18:25: "
But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made."
Luke 12:45-48: "The lord [owner] of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers. And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more."
Ephesians 6:5-9New International Version (NIV)
5 Slaves, obey your earthly masters with respect and fear, and with sincerity of heart, just as you would obey Christ. 6 Obey them not only to win their favor when their eye is on you, but as slaves of Christ, doing the will of God from your heart. 7 Serve wholeheartedly, as if you were serving the Lord, not people, 8 because you know that the Lord will reward each one for whatever good they do, whether they are slave or free.
9 And masters, treat your slaves in the same way. Do not threaten them, since you know that he who is both their Master and yours is in heaven, and there is no favoritism with him
