I think it is not Biblically accurate to suggest Jesus, and Paul taught different doctrines. Especially if you consider ALL of Paul's teaching, and not just the few that can be used to support Mainstream Teaching.
After all, Paul himself said:
Acts 26:20 But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance.
This is exactly what Jesus taught.
21 For these causes the Jews caught me in the temple, and went about to kill me.
22 Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come:
Should we not include these words in our understanding?
