Your beloved LIAR, also claims that Hinduism and Buddhism are cults. What other religions does he call CULTS? Are Catholics members of a cult, too?
The Puritans left England because they denied that THE CHURCH OF ENGLAND was correct and publicly went after it and its head, James, the then King of England.
Once settled in America, they refused to allow Quakers and other non-Congos to practice their brand of religion. That's part of the How and WHY Rhode Island came to be; BTW.
They Cotton Mather, et al, would NEVER have allowed YOU to be a Baptist of ANY stripe and live within the confines of the then Massachusetts.
You said -- "You can't name any other book nor RESPECTED source."
I could; I just don't want to do your work for you. You should do that, if you really want to know.
It's not hidden; it's not a secret; it's well known. It simply takes you searching for that topic and researching the Christian faith and the core essentials and comparing that over and against any other cult. You'll see the differences.
I see no reason to do work for someone else who may be too lazy to do it themselves. I presume you're not too lazy to do that...

P.S. -- If your searching skills are that bad that you can't do it yourself..., I'll do it for you. Just let me know that you're not being too lazy and you just can't find any titles -- and I'll produce a few for you to read.
