So, Jesus said clearly that HE was the TRUTH and that the Scriptures are THE TRUTH.
Intolerance seems to have its origin in monotheism which began as follows: (http://mars.acnet.wnec.edu/~grempel/courses/wc1/lectures/03akhenaton.html)
Akhenaton, tried to replace the traditional, official Egyptian religion of Amarna by a new concept of god. Although still embodied in the sun, this concept, called Aton, was understood more abstractly and monotheistically. This meant that he had to make a revolution. He had to attack and destroy the traditional patterns of religion, which were thoroughly woven into every aspect of Egyptian life. He had to change the theology, ritual and ecclesiastical structure.
Akhenaton was the world's first revolutionary, and he was fully convinc ed that he might entirely recast the world of religion, thought, and life by the invincible purpose he held. Like all true revolutionaries at all times Akhenaton was fully persuaded that his ideas were right and that all men would eventually benefit by them.

According to Josephus, the Egyptian's claimed that Moses was a high priest of this new intolerance. And the exodus was more about being run out of town on a rail. and having a major defeat re-written as an escape and liberation. While Josephus laughed it off as a crude egyptian face saving tale,
Renowned Egyptologist Jan Assmann traces the monotheism of Moses back to that of the Egyptian king Akhenaten (1360-1340 B.C.E.). He then shows how the followers of Moses denied and condemned the Egyptians as polytheistic idolaters. Thus began the cycle in whcih every "counter religion" denounced all others as false. Assmann presents a compelling lesson in the fluidity of cultural identity and beliefs.
