When I was in this situation, I approached the pastor with a ten-page document showing all the relevant Scripture and explaining why he was in error.
Ouch! I think I would have held the door open for you to leave, lol. Kidding, of course.
If I was a pastor or leader in an open assembly the points in your paper would be made into discussion points. The important thing being we're all in this together and that the goal is to make us into fruit bearing trees, not into towers of doctrinal accuracy. We're all learning, we're just at different stages of knowledge and growth and insight, including the pastor. He just (hopefully) has more knowledge and insight to contribute, and the gift to present it--that's why he's the pastor. But he still has to be willing to learn and admit where's he's been wrong.
In a closed, traditional church there is no opportunity for this. It's the pastor/church's way or the highway. He's not allowed to be wrong. The sooner you leave the better. In fact, they want it that way (and I don't blame them). As I say, there are good reasons for that as well as bad. Bottom line......hit the door as quickly as possible so it doesn't escalate into outbursts of anger and a factious division between you and that congregation, both of which are listed as
deeds of the flesh in the Bible. It's okay to dissent, but not utilizing the deeds of the flesh.
People of faith can disagree and still satisfy the goal of growing everybody up into a living, experiential relationship with Christ of living according to the fruit of the Spirit. That is what counts. As long as differences don't fundamentally sabotage that primary goal--and as long as that is the primary goal of the group--then our doctrinal differences don't really need to be the 'make or break' thing we Christians tend to make them out to be.
I have had fellowship with all kinds of people with their varying doctrinal beliefs, but in the groups that met together to learn how to live for God in our daily lives and enjoy his presence, instead of meeting to be doctrinally accurate, those varying doctrines did not divide us.
