Based on Mark 14:71 (and Matthew 26:74) it is common to hear Christian preachers and teachers claim that the Apostle Peter used profanity. This is the passage of Scripture where Peter denies Christ three times. This particular verse deals with Peter's third denial. In some translations it appears at first glance that Peter did indeed use profanity.
(Mark 14:71) "Then he started to curse and swear, I don't know this man you're talking about!" (CSB)
The NASB and NKJV translate this verse in a similar way. It is interesting to note what the HCSB (the original edition of the CSB) has in it's footnote on this verse, "To call down curses on himself if what he said weren't true." Also the NASB footnote on this verse states, "Or put himself under a curse." For further clarification we will look at another translation of this verse.
(Mark 14:71) "But he began to invoke a curse on himself and to swear, I do not know this man of whom you speak." (ESV)
The NIV also translates this verse in a similar way. The ESV translation makes clear the correct meaning of this verse. Peter was not using four letter words. He was actually saying, if what I say is not true let me be cursed. He was taking an oath basically saying let God strike me down if I am lying. Of course Peter repented and was restored by Christ. He went on to become a bold witness for the Lord.
