I'm sorry, let me rephrase the last sentence: through saving faith, Eternal Life is given.
Let me add this: the nature of eternal life is that it is... eternal... therefore, the believer will not lose his/her salvation. S/he is saved for eternity. It is not exactly, "Once Saved-Always Saved" (in fact, OSAS., is a misnomer of the biblical truth) because although s/he will not lose his/her salvation, it is nevertheless, a process.
But the difference between the process expounded by the RCc and scripture is this: the former tells us that we work in cooperation with God in which we, in faith, obey the commandments of God and the Sacraments, and God gives us grace in turn.
On the other hand, the latter states that it is a process done by God, alone.
We are saved, past tense, meaning that we're saved by the promise of God to save us and that He indwells in us (John 5:24 & Philippians 1:6). Then we're saved, present tense: which means that God is continuing to save us (Galatians 2:20). Finally, God saves us, future tense, in which He will surely save us into eternal glory (John 6:37-39 & Jude 1:24).
