Now this guy knows what he's talking about.

I fully agree! But even the "milk" they are feeding people is bad(un-scriptural). Heaven and hell(the "traditional" notion of it vs. the "Biblical" version), praying to Mary or other saints, etc. etc. It is so obvious yet people seem to turn the blind eye? Only explanation I can come up with is "satan's deception is strong," but is it really? Why is it so obvious to some yet most are oblivious? Perhaps no one ever pointed out to them? Yet when you point it out to them, they still defend it... That in itself is the biggest mystery to me.
