The term "ichthys" is derived from the Greek word for "fish." In early Christianity, it became a symbol representing Jesus Christ, as the letters of the Greek word form an acronym for "Jesus Christ, God's Son, Savior." This symbol is often depicted as a simple fish shape and is used by Christians to express their faith. The ichthys symbol is commonly seen in various forms, such as bumper stickers, jewelry, and artwork. It serves as a reminder of the teachings of Jesus Christ and the importance of faith in the Christian community. The symbol has historical significance, dating back to the early Christians who used it to identify themselves during times of persecution.
