 The beatification process commenced in Naples in an informative process tasked in collecting evidence and documentation on Errico's life and possible prospects for being proclaimed a saint.The introduction of the cause came on 18 December 1884 under Pope Leo XIII in which Errico was titled as a Servant of God - the first official stage in the sainthood process.Theologians later deemed his writings to be in line with the magisterium of the faith in 1893 and later held an apostolic process afterwards.
