Yeah! I would totally agree with you. N. T. Wright points out also that pistis is best characterized as loyalty.

But the doctrine of sola fide does not conflict with this at all. Both confessional Lutheran and Reformed say to the effect: “We are saved by faith alone, but the faith that saves is never alone.”

Abiding loyalty is always emphasized as a necessarily true outflow of justification. The doctrine of sola fide is that our belief/faith is the source of our initial justification, but unless there are good works and participation in the sacraments along with that faith, it is meaningless. For both the Lutheran and the Reformed there is no justification unless one is baptized, eats and drinks of Christ, and has good works. However the basis of that is by God’s grace through faith, and not that you were some person who was so morally upright that you could be saved without the cross.

I’m not sure you understand what position the confessional Lutheran or Reformed churches have with sola fide, since this is standard exegesis. I get why you have the position you hold since most evangelical/Baptist/non-denominational churches don’t really get it and think belief alone is what the story is. But for confessional Lutheran and Reformed churches it simply isn’t.
