Resolve the differences about whether we should ask Mary or various saints to pray for us, about which both sides have adamant convictions. Resolve the differences about whether only professing believers should be baptized or also their children. Resolve the differences about whether Scripture alone is the standard of truth, or also tradition. Add to that the vast number of other theological convictions that prevent organizational unity. And make sure your resolution is not coming from a centralized human authority structure. Would you take away the right of these Christians to hold a wide variety of convictions, all based on their belief that their view is what God commands of them? Only Christ has that right to set things straight when he returns, not any organizational structure made by man, which can and has often been corrupted. Until then, freedom of conscience and denominationalism is the way forward.
