The apocrypha, Christianity’s ‘hidden’ texts, may not be in the Bible – but they have shaped tradition for centuries

Of Jesus’ 12 disciples, Saint Peter is one of the most important. In the Book of Matthew, Jesus declares that Peter is the “rock” on which “I will build my church,” and Catholic tradition considers him the first pope. Martyred in Rome in the first century, Peter asked to be crucified upside down so that he would not die in the same way as Christ.
