How Did the ‘Jesus Fish’ or just the ‘Fish’ Become a Symbol of Christianity?
Matthew 4:19: “Follow me, and I will make you fishers of men.”

The first appearances of the Christian fish symbol dates to the 2nd century in Christian art and literature.

The fish symbol held the most sacred significance. Christians utilized it to identify churches and believers during a period of persecution in the Roman Empire. Initially used as a secret the fish symbolized the mission of the group it represented and did so simply and effectively.

The letters of the Greek word Ichthus’ Symbolic Meaning is ‘Jesus Christ, Son of God, Savior’.
This statement affirmed the belief of early Christians in the twofold nature of Jesus Christ being both fully human and fully divine.

The heavenly Ichthus, then, was Jesus Christ, and we are the smaller fishes, born in the waters of baptism, as Tertullian says, caught in the net of salvation, and thus made members of the heavenly kingdom.”
