Moses Maimonides

“ They obligated not only themselves but also their descendants, as it is written, "to us and to our children forever." (Deuteronomy 29:28) . We have been given adequate divine assurance that not only did all the persons who were present at the Sinaitic Revelation believe in the prophecy of Moses and in his Law, but that their descendants likewise would do so, until the end of time, as it is written, "Lo, I come unto thee in a thick cloud, that the people may hear when I speak with thee, and may also believe thee forever." ”

“ God is one in a unique sense of the term, and Moses is His prophet and spokesman, and the greatest and most perfect of the seers. To him was vouchsafed by God what has never been vouchsafed to any prophet before him, nor will it be in the future. The entire Torah was divinely revealed to Moses of whom it was said, "with him do I speak mouth to mouth." (Numbers 12:8) . It will neither be abrogated nor superseded, neither supplemented nor abridged. Never shall it be supplanted by another divine revelation containing positive and negative duties. ”

“ Now, my co-religionists in the Diaspora, it behooves you to hearten one another, the elders to guide the youth, and the leaders to direct the masses. Give your assent to the Truth that is immutable and unchangeable, and to the following postulates of a religion that shall never fail. ”
