I wish I was able to attend service at St Paul's. But it's too far away from me... :/ . Sad to hear that there are no Greek Anglicans
Every seminary is different, but in at least some of them, perhaps in most, those who aspire to the priesthood are taught Greek. Some also learn Hebrew and even "Syriac", that is, Christian Aramaic. I suspect that most of our lay-folk don't know Greek beyond "Kyrie eleison".
Hairete! Have you guys heard of "Dicaeopolis" Our textbooks adopted the poor man from the Acharnians into a rather meh textbook story compared to the Attic comedian.
