Having been a member of a conservative church and a progressive one (not at the same time) and finishing a degree in ministry last year, what I understand about "organized religion" is that it is a construct built by imperfect humans. Therefore, we will have an imperfect product. The key, I think, is pursuing the concept of humility and prioritizing that over ego. If a poor message is produced by the pastor/priest, then you end up with a spiritually unhealthy congregation. In studying the Apostles, they were masters of being humble before God, and when they weren't, those who had direct access to Jesus were reminded of their place. Then is the next step-asking for forgiveness. It is very hard to be humble enough to admit our failings if our ego is in the way. In Revelation, the warnings are given to the churches for poor behavior. The bible has gone through multiple changes over centuries (done by men.) Originally, the 'bible' was all spoken word.

Some are very evil for sure!
