Saint Peter is referenced in Christian biblical canon.
The New Testament or NT ( Ἡ Καινὴ , Hē Kainḕ Diathḗkē ; Novum Testamentum ) is the second major part of the Christian biblical canon , the first part being the Old Testament , based on the Hebrew Bible . Saint Peter ( Syriac/Aramaic : ܫܸܡܥܘܿܢ ܟܹ݁ܐܦ݂ܵܐ , Shemayon Keppa , שמעון בר יונה , Πέτρος , according to the New Testament , was one of the Twelve Apostles of Jesus Christ , leaders of the early Christian Great Church . According to New Testament accounts , Peter was one of twelve apostles chosen by Jesus from his first disciples . Two general epistles in the New Testament are ascribed to Peter , but modern scholars reject the Petrine authorship of both .
