As I said "Most of us sinners are not qualified to make this judgement". Actually, I think that ALL of us sinners are NOT qualified to make this judgement.
So Christians have to accept Hinduism and Scientology as Christian religions, all religions and cults are Christian, or at least so, if they want to claim it?
You don’t accept the Catholic church, the Baptists, the Methodists, the Greek Orthodox, the Lutherans, and so on when they all agree that Mormonism is not a Christian religion?
