Jesus said, "where two or three are gathered together, there am I in the midst,' That is the smallest possible Church. Where ever that happens.
As I said study is really not of much interest to me. It's not a mind thing but a spiritual thing. God is an expert on His Word. You have a lot of negatives there - I'm sure God does not intend ordinary people {for whom the Bible was written} to struggle through all of your points to get to some so called harmony of facts. It stands out that you are never mentioning God in anything you say, and it is His reality that is important. I don't have the time to continue to follow up on your lists of what is wrong with Christianity. We'll have to agree to disagree.
