No, a new manuscript proving the Resurrection has not been found

Claims that a newly discovered 2,000-year-old manuscript containing an account of the Resurrection of Jesus has been found are untrue, according to a report by Aleteia.

The reports stem from a preprint study by Spanish researcher Jesús Fernández-Pedrera Correa. The study has not yet undergone peer review. Rather than presenting a new document, the researcher compared four existing versions of a passage known as the Testimonium Flavianum. This passage is part of the Jewish Antiquities, a work written by the historian Flavius Josephus around AD 93–94.

The Testimonium Flavianum is a section of text that scholars have debated for over a century. It mentions Jesus and his crucifixion, including a line stating that he appeared alive on the third day as foretold by prophets. No previously unknown document has surfaced.
