I think your earthquake line could be omitted entirely as it sounds awkward and unnecessary. It sounds more powerful ending on "power" as it seems a natural end-point and ties up your theme with a much more resounding sonic punch.
With that nitpickery opinion out of the way, I have to say that this is a fascinating piece. To me, you seem to equate your own subconscious desire for faith upon the more ethereal, cyclic and green, as opposed to mountains, or Petros/the Rock (as a Christian-based symbol I immediately thought of).
That stable centre, and having to move it, would certainly be a frightful prospect, philosophically. But therein lies that struggle of polarities. Or, at least, that's how I see it and feel it to be.
This is a work which speaks to me on many levels. And anything which intrigues me, I enjoy far more thoroughly.
I like it...a lot. It has some pretty seedy philosophical undertones.
My advice to you: drop the last stanza.
Stick to the first and third person for this one.
The last part just seems a tad out of place.
Leaving "either that or they cause earthquakes" as the last line gives it more of a cryptic feel.
Interesting thought..."perhaps that is why the faithful leave our mountains unmoved. " Again, I feel as if you should replace "our" with "the". It doesn't lose any meaning that way. It still shows a distinct separation from the writer and the faithful. But a very very good line nonetheless.
