In 1968, he was ordained priest of the Roman Catholic Diocese of Vittorio Veneto, by Bishop Albino Luciani, who later became Pope John Paul I (1978).
Eventually, after founding the Old Catholic Church in Italy, he converted to Eastern Orthodoxy, entering into communion with the Old Calendarist movement.
In 1986, he became bishop of Aprilia and Latium, under the jurisdiction of Metropolitan Kyprianos Koutsoumpas of Oropos and Fili, leader of the Old Calendarist Orthodox Church of Greece (Holy Synod in Resistance).
Failing to achieve canonical recognition, he turned to the newly formed Alternative Synod of the Bulgarian Orthodox Church.
A fraction was headed by his associate, Archbishop Basilio Grillo-Miceli, who created the Orthodox Church of Italy (Italian: Chiesa Ortodossa d'Italia).
