I plead with Euodia and I plead with Syntyche to agree with each other in the Lord. Yes, and I ask you, loyal Syzygus, help these women who have contended at my side in the cause of the gospel, along with Clement and the rest of my fellow workers, whose names are in the book of life.No I don't think I've noticed this passage coming up in the complementarian/egalitarian debate (perhaps I just didn't notice), but it seems to me highly relevant. Firstly, in pleading with the two women Paul is hardly assuming either their submission or his inherent gender based authority. Secondly in saying they contended at his side (along with Clement and others) he is presumable referring either to their joining with him in preaching and evangelism or their participation on Paul's side with internal disputes within the church - all of which render highly problematic the suggestion that Paul did not allow women to teach or have authority.
Let me know what you think :-)
