The actual halo is a bit much but the hat that was a style. I agree it can come off as mockery but I also remember when I first got saved how I gravitated to all that was Christ I know I freaked some people out. Only God know his heart and don’t we have an obligation to nurture our brothers and sisters in Christ as they develop their walk? If we stop to decide who is sincere and who isn’t aren’t we then placing our selves as judges not to the world but to breathen?We were not called to judge but to love and be the example ( salt) If he is or isn’t to me is a moot point. If he is then he needs prayers and Christian support just like any Christian believer and if he isn’t God will deal with him and in a way the still brings glory and power to his kingdom.
