If it was then every time we didn’t perfectly live up to the standards we would not be saved. Kind of like going round and round needing works for salvation isn’t it. No wonder Catholics are confused and not sure of their salvation.
Repeat: Faith and Works are required for salvation.
Every we time we don’t perfectly live up to standards; i.e., fall and sin, we go to confession ...
Faith and works are required for salvation because we have free will. If our will chooses to sin, we turn away from God and jeopardize our salvation. Salvation IS NOT assured - see Revelation 20:12-13 - dead are judged according to their deeds.
Also -Phil 2:12-13 work out your salvation in fear and trembling - doesn’t sound guaranteed.
