This is why I do not take church gigs. There are always politics going on behind the scene.
MM was threatened by you because he realized you know more about how to run sound than he does, and he was afraid to look bad in comparison. So...he set you up.
I used to work for a church. That is where I learned that just because someone is a church-going Christian, or even a pastor, that doesn't mean they are a good person, or honest. They'll stab you in the back just like any other bad person.
Churches are funny. You can be fed spiritually, but you can also run into some of the meanest, most spiteful people you could ever encounter. So...I don't work for them in any way, any more, ever, and if I show up, I just listen and don't talk to anyone if I can help it, other than the smallest of small talk. I've been burned over and over by church people, so I stopped hanging around the fire.

I was right there with you... until about 10 years ago, when I started attending the church I'm at now. It was my "last chance" church because I'd had enough. I grew up a PK (my dad is a pastor for the uninitiated, PK = Pastor's Kid) and saw more than my share of backstabbing and all around bad behavior from Christians. My dad is one of the greatest people I've ever known, one of those pastors who actually walks the walk he's talking to everybody else about on Sundays. Not going into a lot of detail, but he eventually left the ministry for a while and sold real estate after a particularly bad episode at a church he was at for over 10 years... youth pastor, a couple of "his people", some rumors, and a 3 way church split later and dad was finally through. He's back in ministry now, which is good, but it took him and mom a long time to trust anybody again.
Anyway, this church isn't perfect, by any means, but it's the best place I've ever been associated with. Over 2500 people on Sunday mornings and we still meet in a multi-purpose room (read:glorified gymnasium) because rather than spend money on buildings they give a lot away to the poor and needy. We still have building projects, but they're to meet needs not wants. We built a great children's wing recently, and are in the process of building a new office wing and a small chapel to handle weddings and funerals in a more traditional setting than a gymnasium. We always build with cash and always have, no debt - ever. Pastor and his wife make a decent living but not extravagant by any means - about what you'd expect for two degreed professionals, one with a Master's Degree, in our area, probably significantly less than most with those credentials actually. The rest of the staff is likewise paid fairly well, but not out of the ordinary for their skill and educational level. Intentionally multi-cultural, very diverse racially and economically, no favoritism, etc...
After being ready to be done with churches 10 years ago, I'm now considering going to seminary...

Anyway, it takes some looking but there are some really neat churches out there, some big, some small.
