I agree with so much of the 9Marks paradigm.
Sound doctrine? Check! Preach the gospel? Right! Biblical preaching? Oh, yeah! Missions? Amen! Baptism? Discipleship? Right on, right on!!
No women in leadership? Hold on…
You see, they had me, then they lost me.
It’s not so much that I disagree with them on the point. (Which I do, by the way, but honorable people can disagree).
Rather, I’m dismayed that anyone could rank this as of PRIMARY (not SECONDARY or even TERTIARY) importance alongside the blessed gospel. To me this is where SOME complementarian believers go astray, and in the last couple of decades more than ever.
I would no more rate all-male leadership as a doctrinal criterion of the FIRST RANK than I would, DOES THE RAPTURE OCCUR BEFORE OR AFTER THE TRIBULATION, or CAN A CHRISTIAN DRINK WINE, or WHAT VERSION OF THE BIBLE IS BEST?
Count me as having 8 and maybe 2/3 Marks.

Open Our Eyes, Lord! 
it has been discouraging to see what so many representatives of the Gospel and theologians are making “the most important” thing. I fear our witness suffers.
Thanks seeking truth is wise vs the assumption and tradition take care ……
