Is Paul condoning slavery?
He tried to get some of them free, but He did not make a big political scene about it.
Philemon
1:10 I beseech thee for my son Onesimus, whom I have begotten in my bonds:
1:11 Which in time past was to thee unprofitable, but now profitable to thee and to me:
1:12 Whom I have sent again: thou therefore receive him, that is, mine own bowels:
1:13 Whom I would have retained with me, that in thy stead he might have ministered unto me in the bonds of the gospel:
1:14 But without thy mind would I do nothing; that thy benefit should not be as it were of necessity, but willingly.
1:15 For perhaps he therefore departed for a season, that thou shouldest receive him for ever;
1:16
Not now as a servant, but above a servant, a brother beloved, specially to me, but how much more unto thee, both in the flesh, and in the Lord?
1:17 If thou count me therefore a partner, receive him as myself.
1:18 If he hath wronged thee, or oweth [thee] ought, put that on mine account;
1:19 I Paul have written [it] with mine own hand, I will repay [it]: albeit I do not say to thee how thou owest unto me even thine own self besides.
He, speaking about the New And Better Way, had this to say;
Galatians
3:25 But after that faith is come, we are no longer under a schoolmaster.
3:26 For ye are all the children of God by faith in Christ Jesus.
3:27 For as many of you as have been baptized into Christ have put on Christ.
3:28 There is neither Jew nor Greek,
there is neither bond nor free, there is neither male nor female:
for ye are all one in Christ Jesus.
3:29 And if ye [be] Christ's, then are ye Abraham's seed, and heirs according to the promise.
That is the mind of God for us here today.
