Chiesa Ortodossa in Italia
The Chiesa Ortodossa in Italia (Orthodox Church in Italy) was part of the Old Calendarist movement, which then joined Patriarch Pimen's Alternative Synod of the Bulgarian Orthodox Church and adopted reformed Julian calendar (New Calendar).
In 1993, the church joined Patriarch Pimen's Alternative Synod of the Bulgarian Orthodox Church, and in 1995 Bp. Antonio was enthroned as Bishop of Ravenna and Italy. After 1997, Bp. Antonio was elevated to Metropolitan of Ravenna and Italy. During that year, the Orthodox Church in Italy was recognized as an autonomous church, and Metr. Antonio became a full member of Pimen's Holy Synod. The Orthodox Church in Italy is in full communion with Bulgarian Alternative Synod, the Montenegrin Orthodox Church, the Ukrainian Orthodox Church - Kiev Patriarchate, the Macedonian Orthodox Church, and some other small churches.
