LOL -- are you serious?
You might as well be going to some non-aligned protestant offshoot church with a santuary in a shopping mall if your priest has the latitude to pull this kind of shenanigan.
santuary = sanctuary
LOL, no that was my tongue-in-cheek example of the possible response when the priest says things not in the liturgy. If you said this you would be seriously asked to be quiet or shown the door. And yet the priests can, and regularly do, say whatever they want regardless of whether it is in the texts and nobody asks them to leave. Why the different standard for them? That is the height of clericalism, a very specific form of elitism, and we should reject it.
That's what I'm attracted to...A place where the preacher prays from his heart instead of repeating some mindless, repetitious phrase that is engrained in his head...
