Isagoge in canonicas septem epistolas, qua (ut in Paulinis) compositionis oeconomia, et germana dispositio monstratur

AUTHOR OF THE EPISTLE.
The author of the epistle by the consent of all is the Apostle Peter, who by nation was a Galilean, born from the village of Bethsaida; he had a father named John the fisherman, and a brother Andrew, a man of the same profession, with whom he was taken into the Apostleship while he was fishing at the Sea of Galilee, as is in Matthew chapter 4. His name from circumcision was Simeon, which the Lord changed for him, as is in Mark 3 and John 1: You are Simeon son of Jonah, you shall be called Cephas, which is translated Peter. But Ceph or cepha sounds like rock. The Greeks, according to the Attic custom, translated it πέτρον Peter. And because it is a Syriac word, therefore they do not have this clause (which is translated Peter) in their version. Yet in the inscription of this epistle, they joined all three: The Epistle of Peter Simeon Cephas, so that we may understand without doubt that the epistle pertains to the Apostle Peter. Furthermore, Peter seems to be so named because of the constancy and strength of his faith; besides that, he was gifted with singular boldness in questioning the Lord and responding for others, as is to be seen in chapters 16 and 18 of Matthew.
