“There is only one pope”, Pope Benedict XVI affirmed nine years long: he never abdicated, despite confined to a “totally impeded place”. In the Declaratio with which he “resigned” in February 2013, authoritative Latinists immediately identified syntax imperfections, but Pope Ratzinger stated, three years later: «I wrote the Declaratio in Latin so as not to make mistakes». After two years of investigation, patiently carried out by the author through more than 400 articles published in the newspapers Libero, ByoBlu, RomaIT, this gigantic mosaic was slowly recomposed. The scenario that emerges is shocking, of millenary importance, and has not been denied even by the Holy Father Benedict XVI himself. A bestselling book to clarify the Magna Quaestio that will revolutionize the world.
