Metropolis of Paronaxia
The Metropolis of Paronaxia, also referred to as the Diocese of Paronaxia, is under the jurisdiction of the Church of Greece. This diocese has 37 churches, 251 chapels, 18 cemeteries, 18 monasteries and around 35 clerics.
Historically, the Metropolis of Paronaxia is considered one of the original metropolis not just in Greece but in all of Christianity. According to the holy tradition, St. Polycarp, the disciple of St. John the Theologian, visited Naxos and taught Christianity whilst John was in exile on the island of Patmos. To honour this tradition, the island has many churches and chapels dedicated to his honour, especially at the villages of Aggidia Sagri and Filoti, and there is also a church dedicated to John at Keramoti.
During the early Christian period, Naxos was assigned to the ecclesiastical jurisdiction of Rhodes. Tradition holds the St. Helen founded the Church of Panagia Ekatontapyliani - Hundred Doors (Paros) (literally: "church of the hundred doors") during her pilgrimage to the Holy Land 330-337.
There is documented evidence that various Bishops from Naxos and from Paros participated at the Ecumenical Councils  and the Byzantine period was responsible for the erection, on the island, of many large beautiful churches.
In 1083, Naxos was promoted from the headquarters of a bishopric to that of a metropolitan see.
In 1207, the Franks came to the island, under Marco Sanudo, and conquered the Cyclades and founded the Duchy of the Aegean, of which Naxos was made the headquarters.
Naxos, like the rest of the Cyclades, was incorporated into the Greek state as soon as it was founded, in accordance with a protocol signed in 1830.
The current Metropolitan of Paronaxia is His Emminence Ambriosios II (Stamenas) of Paronaxia, born in 1922 on the island of Paros. He was elected and consecrated as the current metropolitan in 1991, replacing His Emminence Epifanios (Kalafatis).

- Theoctiste is from Lesbos, however, due to the archaeological and historical importance of her association with the Church of Panagia Ekatontapyliani - Hundred Doors she is also classified as a Parian local saint.
