"For perhaps he therefore departed for a season, that thou shouldest receive him for ever; 16Not 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?" KJVNo thats not what the letter says!
He wasnt related to onemisis at all he was his servant. But now, that Paul has begotten him i.e Onemisus has become born again, he is his brother. In the Lord.
How can you keep reading things backwards?? Again, what bible version are you looking at?
Notice, in verse 16, Paul refers to Onemisus as a brother to Philemon in two regards. He was a brother both in the Lord AND in the flesh. Now, "in the flesh" could possibly be equivalent to one Jew regarding another as a brother simply because they are both Jews. I am not sure this applies here because these two men are both Greeks just as their names suggest, presumably from Colossae in Asia Minor. The Church at Colossae was a predominately Gentile Church. So, this would seem to imply that these two men were actual brothers in the flesh or they may have even been near relatives and not literal brother. Either way, this would seem to establish their relation according to the flesh.
