In the 1970's there were some ex-Catholic priests in Italy and Portugal (then in Brazil) who converted to Orthodoxy, but as no Canonical Orthodox Church was willing to receive them for several reasons, they got some support from Greek Old-Calendar Bishop Auxentios, who consecrated their leader (Metropolitan Dom Gabriel of Lisbon) to episcopacy. They were later given autonomy that's how the Milanese Synod was born.
They always claimed that it was never their reason to be schismatic or Old-Calendarist but the Canonical Churches had not been willing to receive them. Finaly in 1984, the Church of Poland reluctantly agreed to receive those located in Spain and Portugal but not those in Italy, claiming that it was the jurisdiction of the Patriarchate of Rome (the Italians stayed as the current Synod of Milan).
When Dom Gabriel died, the new Portuguese Bishops started having troubles with Archbishop Sawa of Warsaw and left communion with the Church. The Brazilian Bishops, Chrysostomos and Amvrosios, stayed in communion with the Church of Poland but most of their clergy left them: some of them placed themselves under a Serbian Bishop in Brazil and others formed this Eparchy of Ceara:http://eparquiadoceara.tripod.com/index.html
... previously Ukrainian UAOC-C and now "Hellenic".
If the EP put order here this would not happen, all Latin American Bishops should form an Autonomous Orthodox Church in Latin America, under the EP.
