Ιωάννης (John) is a common name in Greek culture, derived from the Hebrew name Yohanan, meaning "God is gracious." It is often associated with several important figures in history and religion, including John the Baptist and John the Apostle, both of whom played significant roles in Christianity. In the New Testament, John the Apostle is traditionally credited with writing the Gospel of John, which presents a unique perspective on the life and teachings of Jesus Christ. John the Baptist is known for baptizing Jesus and preaching about repentance, making him a key figure in the early days of the Christian faith.
