Where and when did Peter lie?
Peter lied three times when he denied knowing Jesus after His betrayal and arrest, the final time with curses (Mk 14:71). Nevertheless, Peter, like the rest of us, was not a sinless man; however, he was a forgiven man and a faithful Apostle of the faith until his death.
Oh he lied, for starters he denied Christ three times, saying he didn’t know that man.
Do you want one; or two or maybe three examples?
Good grief, vladimir998. Seriously, what are you talking about?
