It should be clear by "a ~1000 year period" that I was talking about history with that sentence, not the present day. For a very long time there was only one Church, the Catholic Church. Any "denominations" were local deviations considered heresy worthy of extermination, and it took the deadliest war in European history (prior to the world wars) for Christians to be able to openly practice beliefs that diverged from the Church.

> So the "employees" of X are untrustworthy, but the collection of circular letters for the "employees" of X is not. This doesn't make any sense.

I am not saying anything about whether the text of various ideologies is trustworthy or next. I am contending that contrary to the original comment I was replying to, it's not actually text that converts people to most ideologies. For Christianity, people generally adopt it for reasons like: being born into a Christian household/society; societal pressure; a desire for community; having received charitable aid when they needed it most; mid-life crises seeking a purpose in life; reckoning with mortality after a near-death experience or losing a loved one; witnessing something they perceive as miraculous. There are many, many reasons people become Christians, but I have never once heard of someone being converted merely by reading the Bible, and I suspect that such an occurence is exceedingly rare relative to all the other means of adoption.
