Peter

Peter is the anglicised version of the Greek name Petra. Used on its own, it refers to one of Jesus's twelve foremost disciples. His name was originally Simon, but Jesus bestowed the name Kaifas upon him, literally, "The Rock". In English translations of the Bible, this is always given as Peter, or as Simon Peter. Greek was more widely spoken than Hebrew or Aramaic, and so it has come down to us from the Greek translation, rather than from the original. It is widely thought that the name Kaifas/Peter indicated the staunchness of Peter's faith in Jesus, but even this was shown to waver when Peter denied three times that he knew Jesus, after the crucifixion.

There are several references to Peter from Bahá'í sources. 'Abdu'l-Baha states that Peter was so uneducated that, when on fishing trips, he would take seven parcels of food, and unwrap one each day, so that he knew which day was the Sabbath (on which day, of course, work is forbidden). 'Abdu'l-Baha also states that it was Peter's increasingly prominent role among the disciples that caused the jealousy, and later treachery, of Judas Iscariot.
