Good point.John2 wrote:I do think, however, that 1 Cor. 15:3 could be based on Is. 53, so that may be an indirect pre-70 CE messianic reference.
"For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures..."
And because the DSS sect was messianic and Isaiah was "one of the most influential books and the one quoted most among the Dead Sea Scrolls" (https://books.google.com/books?id=SBMXn ... ls&f=false), I suspect that they would have seen Is. 53 as a reference to the Messiah, even if they weren't proto-Jewish Christians.
