Hmm, don't hate. But, I'm really going to say forget about it. For some people rules are all that they have. I often wonder what we think will happen when Christ comes back. Will he be interested in all the nice, neat little rules that we've created that in my opinion get us preoccupied and away from thinking about the gospel.
Now, don't get me wrong. Our services need to be decent and in order. But, I think we sometimes lose focus on what's really important. This could be an opportunity for growth for you. I would pray about it. Ask God to direct your path and give you a better understanding of what He requires of you.
I guarantee, it won't involve microphone politics.
Submit to people that are in authority positions over you. But, also realize that often, just because some one is in a position of authority doesn't mean that their lives are spiritually sound. Sad, but true. And, it wasn't the Church that Paul had in mind.
But, in some churches (and, I'm not saying yours is one) but in some churches, it doesn't take much more than a warm male body to be a deacon. In others, there has to be evidence of spiritual growth and they're really strict about the man that wears that hat.
Sometimes at a church, a pastor is less of a leader and more of someone that the church hired to do a job and if he steps out of his place, his church invites him to step outside of the church and look for another job. Again, it shouldn't be like this, but sometimes it is.
I think it's probably most helpful for you to pray and ask God what His lesson is for you in this situation. What would He like you to learn from this experience?
I'm not certain what you meant by calling you out. And, since I wasn't there I can't judge that interaction. It certainly sounds like a negative encounter. If that's the case, I think I would simply back up. Sometimes we learn more by being quiet. This person may have been having a bad day and may not remember the experience the way that you do later. Or could be wishing he/she had not made a big deal of it.
In that case, what would be solved by making something bigger out of it, when you could forget it and push forward with a lesson learned, "quietly".
Otherwise, tempers could flare, and what was spoken hastily with little thought on his part, might later only become worse because we're defensive creatures by nature. And, he'll feel obligated for the world to see "their perspective".
If the person feels totally justified in their position, again, what is gained by a confrontation? Typically, we can't change people's minds, but rather God has to change the heart.
Pray, pray, pray... not only for yourself, but for everyone involved.
