No, I am correctly interpreting the 1st century writings. When they speak f Scripture, the only Scripture they had was Moses (Torah) and the Prophets. So to claim that there is any new doctrine when the 1st century writings do not expound on it as in put it in writing as had been done in the beginning is pure blasphemy. In the beginning YHVH told us that what was given was for ever, that He never changes, that His doctrine has never changed and that neither is it burdensome. So if church doctrine says that YHVH changed His mind, changed His doctrine yet YHVH never had it written down for everyone to see and read, that doctrine is nothing but heresy and is to be rebuked
John 7:16 Jesus answered them and said, “My doctrine is not Mine, but His who sent Me.17 If anyone wills to do His will, he shall know concerning the doctrine, whether it is from God or whether I speak on My own authority. 18 He who speaks from himself seeks his own glory; but He who seeks the glory of the One who sent Him is true, and no unrighteousness is in Him."
Main stream Christian doctrine claims Messiah brought a new doctrine. Messiah says otherwise. I'll take his word over man any day since he was the "WORD" of God that has been from the beginning.
Are you saying that OT ceremonial laws apply to Christians? If not, what conflicting doctrine does mainstream Christianity introduce?
