LOL. So we're "extremists" if we believe Jesus Christ has paid in full for our redemption so that we now stand acquitted of our sins by the work of Christ upon the cross -- the only work that saves anyone.
And who's really "morally self-determining?" The one who rests on Christ's justification alone or the one who says he's working to earn his salvation?
Yes, and James is emphasizing the fact that one must show his faith by works, not be saved by works.
We see the same issue put forth in 1Jn.3:18,
My little children let us not love in word and in tongue, but in deed and in truth.
