If salvation is a process, that really goes to the last breath, per CC, the real question is why get baptized or what does baptism signify ? I would imagine with your definition of salvation, baptism is indeed a part of a protestant. The “confessing with your mouth” is what is done in Baptism,amongst other things. So not to speak for the post starter but baptism plays apart for sure.
Baptism is an integeral part of Salvation, Please take the time to read post #6. I think this will answer your questions.
And yes, Salvation is a process, one that must be worked on every day. It is not a one-time event. The Catholic Church recognizes this. The Catholic Christian answers this question in three stages or levels corresponding to the three meanings the words “saved” and “salvation” has in the Bible:
(Taken from several documents here at CAF and other sources)
•Catholic Christians can respond that they have been saved. This acknowledges the first meaning of “saved” and “salvation” in scripture–Jesus Christ, Savior, by whose act of salvation we are objectively saved–He died, rose from the dead, saved them from sin.
–2 Cor 5:17 So whoever is in Christ is a new creation
•Catholic Christians can also respond that they are being saved. This acknowledges the second meaning “saved” and “salvation” have in scripture–the present experience, God’s power delivering constantly from the bondage of sin.
–1 Cor 15:2 Through it (the gospel) you are also being saved, if you hold fast to the word I preached to you, unless you believed in vain.
•CatholicChristians also respond that they will be saved, that they have hope and confidence that God will give them the grace of perseverance; that they will respond to it; and accept his gift of salvation until their death. This acknowledges the third meaning the words “saved” and “salvation” have in scripture–the future deliverance of believers at the Second Coming of Christ.
–Rom 5:9 How much more then, since we are now justified by his blood, will we be saved through him from the wrath.
PAST EVENT (I HAVE BEEN SAVED)
• Rom 8:24 - for in hope we were saved.
• Eph 2:5, 8 - by grace you have been saved through faith
• 2Tim 1;9 - He saved us, called us according to his grace.
• Tit 3:5 - He saved us through bath of rebirth, renewal by Holy Spirit.
• 2 Cor 5:17 - So whoever is in Christ is a new creation
PRESENT PROCESS (I AM BEING SAVED)
• Phil 2;12 - work out your salvation with fear and trembling
• 1Pet 1:9 - as you attain the goal of your faith, salvation
• 2 Pet 2:20-21 - righteous can fall
• Heb 6:4-8 - believers can apostatize, be damned
• Heb 10:26-29 - those sanctified who sin can still be damned
• 1 Cor 15:2 -Through it (the gospel) you are also being saved
FUTURE EVENT (I WILL BE SAVED)
• Mt 10:22 - he who endures to the end will be saved
• Mt 24:1 - he who perseveres to the end will be saved
• Mk 8:35 - whoever loses his life for my sake will save it
• Acts 15:11 - we shall be saved through the grace of Jesus
• Rom 5:9-10 - since we are justified, we shall be saved
• Rom 13:11 - salvation is nearer now than first believed
• Cor 3:15 - he shall be saved, but only as through fire
• 1Cor 5:5 - deliver man to Satan so his spirit may be saved
• Heb 9:28 - Jesus will appear second time, to bring salvation
• Heb 4:1 - fear of failing to reach salvation
I hope this helps, I provided al the Sriptural references since most Protestants want to know where the Bible says that.
