Can Christians Lose Their Salvation?

"Once saved, always saved—is that true?"

3 Scripture passages2 objections answered2 Church Father quotes

The Short Answer

While God's grace is sufficient for perseverance, salvation can be lost through mortal sin—deliberate, serious sin that severs our relationship with God. Scripture warns against 'falling from grace' (Galatians 5:4). However, salvation can be restored through repentance and Confession.

Quick Overview

The question 'once saved, always saved?' has divided Christians for centuries. Catholics say no—not because God isn't faithful, but because we have free will. Think of salvation like a marriage: God will never divorce you, but you can walk out. Mortal sin is walking out—it's choosing something so seriously wrong that it breaks your relationship with God. But here's the good news: you can always come back. That's what Confession is for. So we live with both confidence in God's love and healthy reverence for the seriousness of sin.

Biblical Evidence

What the Scriptures say

Hebrews 6:4-6

"For it is impossible for those who were once illuminated, have tasted also the heavenly gift, and were made partakers of the Holy Ghost... and are fallen away: to be renewed again to penance."

Why This Matters

The writer describes people who were genuinely saved ('partakers of the Holy Ghost') but have 'fallen away'—showing salvation can be lost.

Galatians 5:4

"You are made void of Christ, you who are justified in the law: you are fallen from grace."

Why This Matters

Paul says these Christians have 'fallen from grace'—implying they were in grace and lost it.

2 Peter 2:20-22

"For if, flying from the pollutions of the world, through the knowledge of our Lord and Saviour Jesus Christ, they be again entangled in them and overcome: their latter state is become unto them worse than the former."

Why This Matters

Peter describes people who escaped sin through Christ but became entangled again—'worse than before.'

What the Church Teaches

Official Catholic doctrine

The Catechism teaches that 'mortal sin destroys charity in the heart of man by a grave violation of God's law; it turns man away from God... and threatens him with eternal damnation' (CCC 1855). Salvation lost by mortal sin can be restored through repentance and the sacrament of Confession.
