" Archaeologists who have explored the catacombs have found a common inscription scattered throughout them. The inscription was the Greek word ichthus, which was used as an acrostic for “Jesus Christ, God’s Son, the Savior.” You might recognize this sign because now these fish symbols are scattered across the backs of cars belonging to Christians. How far we have come when we paste this symbol identified with martyred brothers and sisters in the first century onto the backs of our SUVs and luxury sedans in the twenty-first century. "
