There was another set of scrolls discovered after 1945, more recent. Are you familiar with those.
I'm familiar with a number of scrolls that have been found, both in the 1960s and 2 of them in the last couple of years related to the Bar-Kochba Revolt, but I haven't seen anything that says those texts have any significant religious content at all, much less NT texts. They're mostly military/administrative in nature. If you can post a link to something showing differently, I'd love to see it.
