St. John, also known as the Beloved Disciple, was an apostle and the brother of St. James the Greater. Originally a fisherman and a son of Zebedee, John was one of the first Apostles called by Jesus and was generally known as the youngest Apostle. He, Peter, and James were part of Jesus ‘inner circle and it was only John (of the Apostles) that was present at the foot of Jesus’ cross, and he took Mary into his home. 

After Mary was assumed into heaven, tradition has it that St. John went on to Ephesus. He was then arrested, and the Romans attempted to boil him alive in oil. After John was completely unharmed, he was exiled to the island of Patmos. It was here that John received the vision that inspired the book of Revelation. He also is credited with writing the Gospel of John. He is the patron saint of love and friendship.
