It is often said that we should get used to different denomination/doctrinal views since we will all be in heaven together. I would disagree with that statement. There will not be baptist and catholics and charismatics etc in heaven. There will be no false theology in heaven. There will be people who believed less than perfect theology on earth in heaven, but no false theology. The main point is that all worship in heaven will be perfect too. We are all in the process of being conformed to the image of Christ and we will never be completed in this life which means we will all change when we are glorified. Since our goal is to be conformed to Christ likeness, we should have as our goal proper theology. With that in mine we should never dismiss a topic "because there will be all types of Christians in heaven".
