Here's a simple solution to the problem: fuck religion and don't attend church.
This will not only solve the problem of getting injected with poison, it will solve so many other problems in this world as well.
Hell, just do religion the Japanese way, which is being irreligious, but still going to a temple and/or shrine once in a while (or regularly) as a cultural activity rather than a religious one.
Also worth mentioning that the Vatican, of course, pushed the shots (with the exception of some people, that turned against the Vatican itself because of that). Every major church did and almost all of the small ones too. And by those words and enforcement, people have died and been harmed. Really, religious institutions might as well all be the Church of Satan. By the way, the Russian orthodox church did the same thing and still got a pass from people like Luke Smith, that were saying that the orthodox people are totally based and against the narrative. https://social.076.moe/url/137789
