It is lack of critical thiking that allows true believers like yourself to lump Cults such as Scientology with Catholicism. A little research into the theology of transubstantiation could relieve you of your ignorance.
I’m well aware of the twisted, tortured thinking behind transubstantiation as well as the trinity, a guy who was his own father, the historical development of Christianity and the like. At least Protestants consider communion to be symbolic and at least Catholics and Protestants today aren’t fighting bloody religious wars over such nonsense as they did in the past. Today the belief’s averse affects on many might not be much worse than horoscopes and the like.
