Here we find the roots of one of the fundamental schisms between Protestants and Catholics. Protestants think Catholics rely on “works” for salvation, while Catholics think Protestants rely on faith (without works) for salvation. But for the true Christian, both are present or at least aspired to (my admittedly failed and sin ridden case), so in the end, there is no conflict, at least for the true believer (to which I aspire). In other words, true faith leads to works of faith.
Both are right and wrong. Works without faith are insufficient, as is “faith” that inspires no works. If you have true faith, then works necessarily follow from that faith. Thus both faith (the underlying cause) and works (the evidence of same) are related to salvation. If you are a Christian, the two go hand in hand. If you lack either, then your faith is weak, although weak faith without works is superior to no faith with works.
(Spoken from a Catholic viewpoint, and open to debate, but what I believe.)
I had a friend who made a serious mistake at work that could have caused him a lot of grief. Out of nowhere another guy did some work on his own time to bail my friend out. I said to my co-worker “that sure was nice of “Bob” to do that for you”. The co-worker responded “yeah I guess.” I said “what do you mean you guess? The guy didn’t have to do that.” My friend responded “Hey he didn’t do it for me. You know he’s Catholic and you know how they are. He was just trying to work his way to heaven.” That told me a lot about “my friend”.
