The religious believer is a mental slave to an insubstantial idea, a phantom presence inculcated in a youthful developing mind with the object of control and obedience. It develops with the mind to become a source of mental refuge and comfort, and consequently becomes near impossible to expel.
To claim to be in communication with this phantom does not provide the claimant any special authority for the issuing of moral and ethical diktats which can deleteriously affect peoples' lives.
If a cloistered, life-long celibate, 83 year old man, with no experience of sex, marriage, children or grandchildren professes to give advice on such matters as contraception, abortion, sexual relations, we are entitled to ask for back-up evidence. We are aware of the shortcomings of our own minds, so we are unlikely to be impressed simply with what is going on in his (or his advisors). If he has sincerely-held opinions on these matters, let him set up and fund appropriate research projects in all the relevant disciplines, physiological, psychological, statistical, and, when they are completed, re-present his advice backed-up with credible evidence.
