How did the basic teachings of Jesus combine with the Jewish traditions to make a new belief?

Answer 1

The teachings of Jesus were not combined with Jewish traditions to make a new belief.

Jesus was clear in His teaching that he wasn't adding to what already existed.

Matthew 9:17 Nor do they put new wine into old wineskins, or else the wineskins break, the wine is spilled, and the wineskins are ruined. But they put new wine into new wineskins, and both are preserved."

Paul also makes it clear in his letters that the old ways of Judaism have finished, for example:

Galatians 3:24 Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.

In the book of Hebrews the writer also makes it clear Christianity is not something that has been added to Jewish traditions:

Hebrews 8:6 But now He (Jesus) has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.

Answer 2

A multitude of Jesus's beliefs and teachings had derived from the Jewish religion. Jesus preached that there is one God and accepted the Ten Commandments, both found in the Jewish belief system. Jesus's teachings on mercy and sympathy for the helpless reflected the ideas of both in Judaism. Jesus would also reference Jewish prophets, and defend their teachings as well as mingle them with his own. Jesus's teachings and Jewish traditions contributed greatly to the foundations of a new belief system in Europe.

Answer 3

Jesus taught an expanded version of keeping the Sabbath. He also talked about adultery taking place in the heart, not just in the physical sense.
