Brother's Beliefs

Please pray for one of our church people who has been struggling in understanding and accepting the Trinity. He has embraced a "different doctrine" about the Trinity, which is in conflict with Historical Christian Orthodoxy and especially with a couple of the Salvation Army doctrines. Two of us talked with him today and told him not to propagate his beliefs to others, especially to some of our church members. He said that he'll pray about it. May the Lord speak loudly to Him so that his spirit will be reawakened from his current misunderstanding. May the Lord help him through his "crisis of belief!" We told him that we love him and wants the best for him.
