The term "Ichthys" is derived from the Greek word for fish and is often used as a symbol of Christianity. It is an acronym formed from the initial letters of the Greek phrase "Iēsous Christos, Theou Yios, Sōtēr," which translates to "Jesus Christ, Son of God, Savior." Early Christians used the Ichthys symbol to identify themselves and their faith, especially during times of persecution. The Ichthys symbol typically resembles a simple fish shape and is commonly seen on bumper stickers, jewelry, and church materials. It serves as a reminder of the teachings of Jesus and the importance of faith in the Christian community.
