I like the ambiguity in the last line. I'm not sure if this is how it's meant but I sort of read it as is the church non-essential to the important aspects of the religion, I suppose is the building an essential part of the whole community. Or maybe you are just questioning the beliefs.
I wonder if you need some punctuation after right, or if you have deliberately left it blank. I think a question mark could be used to show the thoughts of it, or an ellipsis to show the thought is leading on to bigger questions.
