Timothy was a faithful companion and disciple of St. Paul, who regarded him as a spiritual son. Timothy's mother Eunice and grandmother Lois passed on the Faith to him. Polycrates, an early Bishop of Ephesus writes that Timothy was Bishop of Ephesus, when St. John the Apostle arrived there. St. John stayed for a time with Timothy, but then was exiled to the island of Patmos during the persecution of Domitian. Timothy remained Bishop of Ephesus until he was beaten to death by pagans when he was more than eighty years old. Two of St. Paul's epistles are addressed to Timothy. Timothy is mentioned in the Acts of the Apostles and in several of St. Paul's letters.
