There is a common misconception with some Jewish people that Jesus teaching was contrary to the Pharisees. Searching the Mishnah (the early portion of the Talmud) which is an entirely Pharisaic document, we could find similar teaching. Of course, we know that the Lord Jesus came up with the Law of Perfection. Below are some examples with a few comments:
1. Jesus taught that the Sabbath was made for man, not man for the Sab-bath. (Mark 2:27). In the Talmud, Yoma 85b, Rabbi Jonathan ben Joseph said: “For it (the Sabbath) is committed to your hands, not you to its hands.” Jesus showed us by example to rest from our daily work on the day of the Lord, go to the place of worship, and do something good to our fellow men as He went to the synagogue and healed the sick.
2. Jesus said, “Whatever you want men to do to you, do also to them.” (Mat. 7:12) In Tosefta Sh'vuot, ch. 3, we learn, “One who betrays his fellow, it is as if he has betrayed God.” Please note that Jesus presented the principal in the positive way meaning to do something positive (doing good things) rather than not to do something negative (doing some-thing bad).
3. Jesus taught that Insulting some-one is like murder. (Matthew 5:21- 22). In Talmud: Bava Mezia 58b, we read, “He who publicly shames his neighbor is as though he shed blood.” We notice that Jesus wants us to be gentles with everyone in the whole world and not only to our neighbors. 4. Jesus said, “But I say unto you, that whosoever looks on a woman to lust after her has commit-ted adultery with her already in his heart.” (Matthew 5:28) In Kallah, Ch. 1, we learn, one who gazes lustfully upon the small finger of a married woman, it is as if he has committed adultery with her. We notice that Jesus wants us not to lust after any woman, married or not married. She is a daughter of God, created after His image with intelligence and immortal spirit and we have to deal with her as such.
Jewish Expectation of the Messiah "when he, that is the Messiah, comes then he will heal the sick, resurrect the dead, and to the poor announce glad tidings.” (4Q521, Dead Sea Scrolls at Qumran)
The purpose of Jesus was not to do miracles but to save us from eternal damnation. He showed God’s love to us by bearing the punishment of our sins on our behalf, healed our corrupted nature through the sacraments of baptism and confession, united us with Him through the sacrament of communion, and enlightened the way of eternal life for us.
God wants everyone to be saved, Jews and Gentiles: “And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.” (John 10:16)
Compare with Exodus 12:48-49 “And when a stranger shall sojourn with thee, and will keep the Passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
One law shall be to him that is home born, and unto the stranger that sojourns among you.”
Circumcision was a symbol of Baptism through which we remove the filthy part of our humanity which is the old nature that was corrupted by sin and we become children of God.
