Christianity has long held its level of morality to be the highest, and superior to that found in Judaism. However, as this class shows, Christian moral teachings, found here in the Sermon of the Mount, are actually all Jewish teachings. This class shows how Yeshu's original teachings were all founded in previous Torah literature.
When Yeshu spoke, there were then no Christians, or Christianity. Yeshu was speaking about Judaism, and he was speaking exclusively to Jews.
Essentially, what we have here is the Torah of Yeshu, and we find it to be completely in line with and in context with the traditional Rabbinic teachings of his day.
This is no new revelation. Church Fathers saw this centuries ago.
Readings from Rabbi Gerald Friedlander's 1911 book called, The Jewish Sources of the Sermon on the Mount.
The important of being the light of the world, the light unto the nations. This light is not the Gospel, there was no Gospel when Yeshu spoke this. He was referring to the Torah, and how Israel and the suffering servant in Isaiah, serves Heaven by shing the light of Torah to the world.
Various other Jewish laws and observances are discussed. Each show how Yeshu was following the traditional Rabbinic edict to make a fence around the Torah.
The Sermon of the Mount is an example of a traditional Torah derasha of musar. There is essentially nothing Christian about it at all.
