I think that His Holiness the Dali Lama said it best..............................
"I like your Christ, but I do not like your Christians. They are so unlike your Christ."
Dogma screws everything up, because it's used to divide people into pure people and sinners, and every church is claiming to be the "right" one.
Anyone ever consider that God is too large to be contained in just one religion or dogma?
Did you ever consider that the worlds religions don't agree on much of anything so they can't all be right?
Actually, most of the world's religions do agree on quite a bit................
They all believe there is some Higher Power, God or whatever you wish to call it, somewhere behind the scenes, watching how their creation turns out.
They all believe in some concept of Hell, and they all believe in some concept of Heaven.
They all believe that what we do in this life now, will determine what happens to us later.
They all have some form of rules that tells us how to treat our fellow man.
But, you're right.............many religions DO disagree, and that is because of the way they interpret their books, i.e. their dogma.
