Jesus Fish Secret Symbol Ichthys ΙΧΘΥΣ Son of God 6 Cm Round Badge

From Wikipedia: "The ichthys or ichthus (/ˈɪkθəs/[1]), from the Greek ikhthū́s (ἰχθύς, 1st cent. AD Koine Greek pronunciation: [ikʰˈtʰys], "fish") is (in its modern rendition) a symbol consisting of two intersecting arcs, the ends of the right side extending beyond the meeting point so as to resemble the profile of a fish. It has been speculated that the symbol was adopted by early Christians as a secret symbol; a shibboleth to determine if another was indeed Christian.[2][3] It is now known colloquially as the "sign of the fish" or the "Jesus fish""
