Certain skeptical theories claim that Jesus is a Piscean fish god, arguing that upon his resurrection he is made to ask, "Do you have any fish?" in Luke 24:41.

However, the request in Luke 24:41 was for brosimos, or meat, which was a synecdoche for anything that was edible. This did not establish the choice of communion food of a new astrological age, nor is there evidence of fish being used in early Christian communal meals. The custom of eating fish on Fridays is a much later tradition that has no bearing on the first-century text.
