While in Palestine he met Father Custos Ferdinando Diotallevi, the new head of the Custody of the Holy Land, who had the plans Barluzzi had previously drawn for Mount Tabor during his first visit. He requested Barluzzi start work simultaneously on this and another church at Gethsemane. Worried by this new responsibility Barluzzi returned to Italy to take advice, but ultimately returned to Jerusalem decided and determined. By 1924 he had completed The Church of All Nations at Gethsemane and the Church of the Transfiguration on Mount Tabor. A strong nationalist, Barluzzi was secretary of Jerusalem branch of the Fascist Party from 1927 to 1937.
