“The Revelation at Mount Sinai is the core of Judaism.
And this not only because it is the beginning but because it is apprehended as a total and all-inclusive revelation.
That is, this revelation is considered the opening point, the transition point, between the higher essence and the lower essence – between God and man.
After this revelation there is actually no need for a new revelation because besides being the first or original of its kind, the Revelation is a one-time event that includes all the other revelatory events.
It has been compared to the primordial act of the creation of the world, which was also a first and single act and included all that was and will be in the world.
So, too, the Revelation at Mount Sinai is such a unique event containing in it all that afterward will ever be made known about the connection between God and man.”
