I name all my religions to custom names.
For example when I played The Mayans I named their religion "Mayanism" with the muslim star and moon symbol, ´cause you know the mayans where into astrologi. Then when I played as Spain I had planned to name all the ships, islands, wars and other things to spanish names, ´cause how else am I going to use the spanish we learn in school for. Then some rounds into the game it was time to create my religion. I named it "The Gate of Heaven" because I choose the Shintoisms symbol that looks like a gate. Then I facepalmed because I realize I should´ve named the religion "La Puerta del Cielo" which is spanish for "The Gate of Heaven".
