Interesting, cheers. He didn't, you're right... he more sort of pointed a current one in a different direction. You've got the Disciples and Paul to thank for Christianity... I'm not a massive fan of the organised church as it is in its current state, but oh well this is off topic.
Throwing my response in here so as not to derail the other thread.
From everything that I have read/my belief is that Jesus didn't give a new direction. What he was doing was fulfilling the Father's plan, and he followed the Torah entirely (that is being without sin).
What he was speaking out against was the Pharisaical Judiasm, which is nothing more than another man made religion. They have the rabbi-written Talmud, which they place higher than Torah.
Christianity twists the words of "Jesus" that he speaks in reference to the "tradition(s) of the elders" to mean He was anti-Torah. That is rediculous if you realize that "Jesus" had to follow Torah perfectly to be sinless, since sin is transgression of Torah.
When the Pharisees/Sadducees were accusing Him of sinning, he wasn't breaking Torah, he was breaking the traditions and rules in the "Oral Law" (Talmud).
Judaism was not created by the "God of the Old Testament" and Christianity was not created by "Jesus, the God of the New Testament. Both are man made religions with bits and pieces from the Bible woven in
YHWH/Yeshua are one entity with the same plans and instruction. Yeshua could not have been contradicting YHWH or he would have been a false prophet/messiah.
Paul and the disciples did not create Christianity, Paul followed Torah as did the other disciples. Christianity as we see it today came from the very group the writers of the NT warned against; The "Nicolaitans". They taught that just having an intellectual knowledge of God/Jesus was saving, and Grace gave free license to do whatever you want.
The First Council of Nicaea created an organized man made religion that was an amalgamation of misinterpetated passages from the NT and a wide slew of pagan practices, for the purpose of consolidating Constantine's power and bridging the diversity of his common people.
Since then Christianity has splintered into hundreds of sub-religions and denominations. None of which believe in following the entire scripture.
