The modern understanding of repentance as “feeling sorrowful,” “doing penance,” or “turning from sin” owes far more to Jerome’s Latin Vulgate translation than to the actual Greek New Testament.
In the original Greek manuscripts, the word translated “repent” is μετάνοια (metanoia), which literally means:
meta – change
noia – mind/thought/understanding
So, metanoia = a change of mind — especially regarding belief in the truth about Jesus Christ.
When Jesus and the apostles said “repent and believe the Gospel,” they weren’t demanding a person clean up their behavior or show external signs of remorse. They were saying: “Change your mind about who Jesus is — believe that He is the Christ, the Son of God!”
But something changed…
In the late 4th century, Jerome, a Roman Catholic scholar, translated the Bible from Greek into Latin. In doing so, he mistranslated “metanoia” using the Latin word “paenitentia” — from which we get the English words penance and penitence.
“Paenitentia” does not mean “change of mind.” It means remorse, sorrow, or acts of penance — a concept foreign to the original Greek.
This translation reinforced a works-based view of salvation by suggesting that repentance means feeling sorry, confessing sins, doing penance, or making amends — rather than believing the truth and trusting in Christ alone.
This linguistic shift became a theological one, deeply embedded in:
Roman Catholic doctrines of confession and absolution
Protestant Lordship Salvation teachings that demand a “life change” to prove faith
Modern Bible translations and evangelism that say “repent of your sins” (a phrase that never appears in the Bible)
This mistranslation helped lead to centuries of Gospel confusion:
People began thinking they had to “turn from sin” or “feel deep sorrow” before they could be saved.
Assurance of salvation was lost, replaced by endless introspection: “Was I sorry enough? Did I repent enough?”
Salvation became seen as a process of self-reformation rather than a moment of belief in Christ’s finished work.
“He that believeth on the Son hath everlasting life…” (John 3:36, KJV)
“Repent and believe the gospel.” (Mark 1:15) — Literally: Change your mind and believe!
It is not “Repent of your sins and believe” — that’s adding to the Gospel (Galatians 1:6–9). It’s not “Do penance and believe.” It is: “Believe.”
The true Gospel was never about behavioral reform but about believing on Jesus Christ. Metanoia is the internal shift — from unbelief to belief. That’s what saves.
The penitent/penance idea was inserted by Jerome, not the Holy Spirit.
It’s time to undo that error and return to the clarity of the original Greek:
Change your mind. Believe in Jesus. Be born again — once, forever, freely.
