Except that the old covenant didn’t pass away, it was renewed. He said he didn’t come to abolish, and that not one jot or tittle from the law would pass away.
Also James called Paul in and James, Peter and John told Paul to go purify himself with other vow takers, to show the Gentiles that he still abided by the LAWS. And this was 30 years AFTER THE CROSS.
Where??? When??? When the Temple was destroyed in 70 AD and the priests were slaughtered, there was no sacrificial system left to execute the Mosaic Law. The message of the Gospel was telling the Jews that Jesus Christ was the fulfillment of the OT -- the Mosaic sacrificial system and the prophecies.
He said he didn’t come to abolish
Right, He said that He came to fulfill and that He did.
and not one jot or tittle of the law would pass away
Right, and we have all those jots and tittles in our Bibles, the same jots and tittles that Jesus came to fulfill and did fulfill -- though there are some still remaining to fulfill at this second coming.
