I don't think all paths lead to the top of the mountain. In fact, I don't think the paths are all that important. I think what we're carrying on the path is more important.
I think Jesus modeled "the way" to get to the top and it wasn't about a religion but a perspective. There are people in all religions (and none) with that perspective.
A lot of time is spent on paths... maybe not enough on what we're carrying?
