Sectarianism and Schism

The world's extant religions have without exception fallen prey to sectarianism and schism that have preoccupied and divided their followers to such an extent that the true spirit of the Teachings of the Authors of their respective Revelations has been so obscured that the spiritual effect which these Teachings have had on the hearts of men has been progressively weakened. Sectarianism and schism have stemmed from differences over interpretation of the Holy Scriptures and the introduction into the original Teachings of man-made dogmas and rituals. 
Had the Founders of the past great religions made specific provisions concerning the matter of succession; that is, had they formally designated a successor or established a system whereby a successor or series of successors would have been endowed with unequivocal authority to interpret Holy Writ, there would have been no basis for the divisive interpretations that have sundered these Faiths, even in early Christendom, the institution of the Papacy and hierarchy of the Church had as the sole basis for its authority their interpretation of the meaning of a verbal statement that Christ had made to His Apostle, Peter. 
While this authority remained unchallenged for centuries during which time the Church remained united, it was ultimately challenged by the Protestant movement with the result that today Christianity finds itself divided into hundreds of sects.
