When it's a charismatic variation of the religious framework, if you close your eyes it's nearly impossible to tell if you are in a pentecostal Christian gathering or a charismatic Catholic one...

Yet both sides would be staunchly against the 5% differences in their house of worship decor and the theology. 

Is that truly of "God", is one side really right and the other really wrong?

Or is the truth found merely within, through one's own direct connection with the Divine?
