Many religions have given the religious prerogative to certain individuals to the exclusion of all others. People’s faith and worship is conditional on the consent and approval of these individuals. According to these faiths, the individuals act as intermediaries between people and God, granting forgiveness and claiming to know the unseen and consider those who oppose them doomed to utter loss and misery.
