In this study we tested the Catholic dogma of transubstantiation by DNA analysis. Results showed unequivocally that the rituals performed by the priests during the Eucharist sacrament have no detectable effect on the substance of altar bread at the DNA level.
Very amusing, but pointless. The reason the doctrine is called “transubstantiation” instead of “transformation” is because when Catholics say “transubstantiation” they mean something very different from transformation. And it all goes back to Aristotle.
