Ichthys Symbol - The Christian Fish Sign Meaning and History #1515399 (License: Personal Use)

This minimalist black-and-white Ichthys symbol-formed by two intersecting arcs resembling a fish-is one of Christianity’s oldest visual identifiers. Originally used by early Christians to recognize fellow believers covertly during Roman persecution, it derives from the Greek word “ἰχθύς” (ichthys), an acronym for “Iēsous Christos Theou Yios Sōtēr” (Jesus Christ, Son of God, Savior). Today, it remains widely recognized on car decals, jewelry, and religious materials.

Used on religious websites, educational pages about Christian symbolism, church outreach materials, and theological blogs; matches user intent seeking historical, theological, or cultural understanding of Christian iconography.
