I need some help with a word

I am in need of some feedback on the creation of a word to describe the view that conventional religions are inadequate human attempts to concretize our experiences of the sacred and holy, which transcends us all.  This perspective calls people to a universal spirituality that surpasses conventional religions.  

I don't want to use transcendentalism because it is used to describe a specific American literary and philosophical movement.  Neither do I want to use the word universalism because it is already in play to mean all sorts of things, and not this.

So what are the choices and what sounds the best? 

Please leave me a note with your preference or another idea that might work better.

1. transcendentism

2. transcensionism

3. transcendism

4. transcendalism

5. transreligionism
