The fish is an ancient symbol of Christianity. The early church used it as a secret code for identifying each other in places where their faith could get them killed. They combined the letters in the Greek word for fish, ΙΧΘΥΣ (ichthus), into an acronym for "Jesus Christ God's Son Savior". The fish symbol also served as, and continues to be, a reminder that we are called to be "fishers of men" by spreading the message of Christ.
