In 2020, the Marcionite Church learned of plans by the Vatican Apostolic Library to digitize and make public 40 million pages of documents. A small team of archivists led by Chancellor A.W. Mitchell was tasked with finding anything related to St. Marcion's banned and long-lost book, 'Antithesis.'
But during the search they found something shocking - a tranche of digitized manuscripts proving that St. Jerome (Hieronymus) used Marcionite Church Greek source material to translate the apostle Paul's epistles to Latin. You will note that only ten, along with their original prologues, are directly attributed to St. Marcion.
However, when the Catholic Church released their own version of a bible in 382 A.D., the number of Paul's epistles magically expanded to 13. And of the original ten, their contents had been carefully edited and Judaized to 'harmonize' the beliefs of an alien religion reflected in the Old Testament.
The original ten epistles, including their prologues, can still be found in
The Very First Bible.
