The First Epistle of John
These epistles are written by the Apostle John, who wrote five books in the New Testament: the three epistles of John, the Gospel of John, and the book of Revelation. He was a close friend of our Lord and was loved by Him. His brother, James, wrote the epistle of James.
These three men, Peter, John, and James, were closest to our Lord and were present at the transfiguration. All three were fishermen on the Sea of Galilee.
