I am reminded of a bible study I attended led by a Jesuit priest .  A member would show up now and then and debate the topics using Buddhist ideas.  The priest was very patient till one day he said to him in front of all of us that it was a catholic study and no more input from his Buddhist alternative thinking would be welcome.  He stopped coming all together. The man later jumped to his death over a bridge. The priest told us he had met with him many times one on one and had invited him to the study, but that he had emotional problems and was very  sad about his death. There are reasons people do not grasp what is True and turn to substitutes.
