One passage Fundamentalists often cite as a proof against the Catholic view of salvation is Ephesians 2:8-9: "For it is by grace you have been saved, through faith-and this not from yourselves, it is the gift of God-not by works, so that no one can boast."
Though this passage can often stymie Catholics in conversation, it is nothing to be threatened by.
Even if we assume that Paul is speaking of "good works" when he says we have not been saved by works, this in no way conflicts with Catholic theology. Notice that the passage speaks of salvation in the past tense-"you have been saved." In Greek this is the perfect tense, which denotes a past, completed action. (more below)
