What did Jesus teach was the work that God required to be Saved, when the Pharisees asked Him what must man do to have eternal life? What did Jesus teach Nicodemus in John 3 when Nic came asking questions?
What did Jesus tell the rich young man he had to do in order to be saved? Oh, right: Go and give all you own to the poor. What did John tell the people they had to do? Oh, right: Repent.
The dispute between Catholics and Calvinists over sola fides isn’t over whether faith is salvific. Of course it is. The argument is over whether faith can be salvific without works. And the Catholic position is that salvific faith inherently is accompanied by works. Faith without works is like a triangle that doesn’t have three sides.
