A month later, a reply came back from the Pope in Roma. He recognised Leon Battista Alberti's resignation as the Emissary, but unexpectedly the Pope sent a request to Antonius at the same time, requesting to set up the Vicariatus Apostolicus Thessalonicensis, hoping that the Caesar is able to officially recognise the growing Catholic population inside the city, as a return appointed his old friend Leon Battista Alberti's as the archbishop, giving him a nice sum of funding on improving the standard of education of Thessaloniki just as what Antonius has planned, promising that the Vatican shall not seek to spread their influence in to his territory further.
