The "Epistles of John" refer to three letters found in the New Testament of the Christian Bible, traditionally attributed to the Apostle John. These letters, known as 1 John, 2 John, and 3 John, address early Christian communities and focus on themes such as love, truth, and the nature of God. They emphasize the importance of living in accordance with Christian teachings and warn against false teachings. Each epistle serves a distinct purpose; 1 John discusses the nature of God and the importance of love, while 2 John warns against deceivers who do not acknowledge Christ's teachings. 3 John is more personal, addressing a specific individual named Gaius and commending him for his hospitality towards traveling teachers.
