I'm a Methodist PK. The thing for me is that as a PK you have a window into the dark underbelly of the church through talk around the house. You know of the political battles over trivial matters, and a lot of actions, sayings, and occurrences that simply don't sound very Christian. It grows tiring.
It is easy to say, "well, I'm done with that." I tried that for awhile. Staying away from church made me realize that, as bad as it is, it is the best thing I have to nurture faith. So, I went back.
I have modified my participation which rather annoys my pastor who espouses that members should be involved in one or more groups in the church to keep them engaged. I go to worship. Period. They can have their cliques and petty political squabbles. I am disinterested. I've been involved in teaching Sunday School and served on administration committees. I have now quit all that. I go to worship. And, I go home to live out the gospel.
P.S. I also don't do pot lucks and will never eat someone else's green bean casserole as long as I live.
