Nothing more is needed than his ratification of Moses (Mat 5:17-20)
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
I kinda like Acts 111:4-7
4 Starting from the beginning, Peter told them the whole story:
5 I was in the city of Joppa praying, and in a trance I saw a vision.
I saw something like a large sheet being let down from heaven by its four corners, and it came down to where I was.
6 I looked into it and saw four-footed animals of the earth, wild beasts, reptiles and birds.
7 Then I heard a voice telling me, Get up, Peter. Kill and eat.
It's kinda reinforced in Acts 15; too.
To the contrary - Kosher is the norm in Judea among Hebrews. It is YOUR claim that is extraordinary, not mine.
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
'Abolish' and 'fulfill' are Rabbinical terms - Wouldn't it be useful for you to find out what they mean?
I kinda like Acts 111:4-7
Ahh, yes... The 'Meats and Sheets' vision. Two things:
First, it shows Peter declaring that he was keeping kosher 15 YEARS after the cross.
Secondly, Peter interprets the dream himself at the house of Cornelius: 'Do not call unclean what YHWH has made clean' was referring to the Gentiles, who were never made 'unclean'.
