Catholics and Orthodox share common forenames and family names, as well as traditions, especially on the islands . The constribution of Roman Catholics to neohellenic literature during the last centuries is not negligible.
Tourism is another factor contributing to mixed marriages.
The majority of Catholics are, unfortunately, established in Athens , a city of about 4 million people. There are Catholics in Corfu, Patras, Thessaloniki, Kavala, Volos and more distant islands like Rhodes, Kos, Crete, Naxos, Santorini, Samos, Chios, Kephalonia, Zakynthos, e.t.c. There is a Catholic Church in Nafplion, another in Aspra Spitia which might be helpful, to the Catholic tourists visiting, Epidavros, the Peloponnese, Delphi and Beotia. In addition to the Roman Catholics who repesent the majority of the faithful, there are about 3.000 of the Byzantine rite and a few hundred Armenian Catholics. Thisdiaspora, even in large towns, makes the postoral work of priests and religious very hard.
