Remember, the goal of the narcissist is to satisfy their desperate need to always feel superior to you. They do that by always being right. Being right is more important to them than the truth. That's why, for example, in one argument a person will say believers never stop believing, then in the next argument, when it suits them, that person will say the believer is still saved even if he stops believing. The need is to be right, not search out the truth. Truth is the narcissist's kryptonite.
They will say whatever they need to say to be right. And they will do whatever they need to do to be right, which includes provoking you to respond in an uncivil manner so they can appear morally superior to you. If they can't win an argument on facts, they will attack you personally in order to provoke you to bad behavior. Anything to maintain the desperate need to feel superior to you.
I'm sharing this so some people here can recognize this about themselves and prepare themselves for the return of Jesus. And so the pages and pages of unjust treatment of others in this thread can finally come to an end. After all, as Chris1975 pointed out, that's what this is all about. Christianity isn't about having correct 'religious' doctrine. It's about having doctrine that changes who you are.
