All of these horror stories of musicians playing in church bands. I am not trying to start a fight here and am NOT making this at all about religion and WILL NOT tolerate attempts to make this a religious conversation. I know you have beliefs... good for you, proud of you and glad you made that decision, but a church band is there because the church need Background music. Start a band. Play to be heard.
Churches may as well run a karaoke track for the amount they appreciate a band. Sure, I know, you do it for love etc etc, but playing music is one of the greater creatives. You should be able to write and express yourself, talk to and with your audience and have them come to venues and see you play. Ever broken a sweat at a regular church gig? Ever had someone scream out a request or had a crowd cheer after a song you wrote?
Way off OP, just sad hearing all these stories of people buying gear with the intention of it being played so low that it is barely heard, with sound guys complaining when it is.
A worship band is their to worship their God and to lead worship for the whole church body. When we need background music, after or before services, we do play a track through the PA.
At our church, we DO write our own material often. Generally out of each service, we get four songs played and one of them is an original. We also talk to and pray with our audience. A lot of modern churches do this.
We also get requests, but not usually while we play. People ask us to play songs they've heard off the radio more often because they know we will play our originals each service anyway. Generally, the song selection is also tied with what the message/preaching/sermon/whatever is for the day. For example, we have a few original songs written based on the book of Joshua. When the pastor is going through this book, we will play these originals more so because it helps link the worship service to the rest of the services.
You seemed to get really defensive over the mentioning of how people are gigging. We weren't sharing our beliefs in the slightest. This reaction was a bit much. If you replaced the word church with bar, it would not have changed the content at all. :/
