Satoshi expostulated, "Do you not realize I’m speaking about church leaders who expound such differences to their followers?"
At high enough temperatures, distinctions in physics disappear. Electrons, protons, neutrons, etc all become quarks. Einstein showed that E = mc², but matter and energy become not only equivalent, but indistinguishable and inseperable at temperatures like the early universe.
Similarly, with severe enough persecution, distinctions between Christian groups disappear. In a prison camp, rules about communion between Catholic/Protestant are suspended. My high school chemistry teacher had a poster, "In the event of nuclear attack, all rules against praying in school are temporarily suspended." It is said that there are no atheists in foxholes. (I haven't served, myself.)
