Contradiction with Proverbs 26:11
This verse parallels rather than contradicts 2 Peter 2:22, as both use the metaphor of a dog returning to its vomit to describe a foolish return to one's folly.
Proverbs 26:11: As a dog returneth to his vomit, [so] a fool returneth to his folly. [returneth to his folly: Heb. iterateth his folly]
Contradiction with Luke 15:7
This verse suggests that there is joy in heaven over one sinner who repents, indicating the hope for redemption rather than the inevitability of returning to sinful ways as implied in 2 Peter 2:22.
Luke 15:7: I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
Contradiction with 1 John 1:9
This passage emphasizes forgiveness and cleansing from unrighteousness upon confession, which contrasts with the pessimistic view in 2 Peter 2:22 of a return to past sins.
1 John 1:9: If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness.
Contradiction with Isaiah 1:18
Here, the promise of sins being washed clean by God contrasts with 2 Peter 2:22's implication of repeated backsliding and impurity.
Isaiah 1:18: Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Contradiction with Romans 8:1
This verse speaks of no condemnation for those in Christ Jesus, suggesting continued renewal, which contrasts with the view of regression found in 2 Peter 2:22.
Romans 8:1: [There is] therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Paradox #1
The potential contradiction with 2 Peter 2:22 could be with the idea of salvation and whether someone truly saved can return to a sinful life. Some interpretations suggest it raises questions about the permanence of salvation and if true believers can fall away from their faith, which conflicts with certain doctrines of eternal security.
Paradox #2
This verse is seen by some as having a contradiction because it suggests that people who return to bad behaviors after knowing better are irredeemable or foolish. This can conflict with the idea of forgiveness and redemption central to many Christian teachings, where everyone can choose to change and be forgiven regardless of past mistakes.
