Most religions are valid ways to God. I hear this often. It's very popular. A corollary to this belief is that most religions believe basically the same things, with minor differences. I'd say that most religions are fundamentally different, and only superficially the same .
Religions distinguish themselves on their uniqueness.
So, to tell them apart, you must look at what their fundamentals say. At least one major religion claims to include all religions, but this in fact perverts all of them by rejecting their doctrines. Most religions cannot be valid ways to God, because most religions are not fundamentally the same . That's a difficult pill to swallow for someone who believes that there are many ways to God. Jesus didn't just claim that He would just show the way to God.
