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.
And Calvinists believe that Jesus didn't die for everyone's sins, just ours. You can see why there were so many bloody wars.
Problem is your choice is to be a reductionist, materialist, follow scientism, or to have a religious worldview - whatever form that may take. Chances are you have one as well.
And if you think the Trinity is tortured thinking, try quantum physics.
Terms such as “Twisted” and “tortured” belie your prejudice. Your inability to comprehend a concept as spiritually sound as the trinity only demonstrates your earth bound consciousness. Paul called it “animal consciousness.” Suffice it to say you are not reborn, in Christ’s terms, a spiritual creature with knowledge of spiritual matters.
