Since all the great religions were originally taught by Godís own chosen prophets, they had to be the same basic message. We do see differences, however, between them and we have to examine how this happened. After the time of every prophet, his teachings were either forgotten or distorted. Also, as a result of the changed circumstances of later times, newer and newer interpretations were introduced into the religion and gradually the essential message was polluted. This was the reason for the existence of a plurality of religions, in the place of the single Religion of God which all the prophets taught.
