You make me jealous. An icon of St. Dioscoros on papyrus. How did you get it? Mind taking a picture of it? I’d love to see it.
Could I call you “Cre” for short?
I picked it up in one of our several great Coptic cathedrals here in Toronto in their bookstore. I’m not very savvy with the tekky stuff, but if you Google him, icons will come up.
The Coptic gentlemen who were behind the counter in the bookstore feigned some surprise when I told them I was a UGCC Chalcedonian . . .

But then one of them waved his hand and said, “But in these ecumenical times . . .”
Personally, I think that one of the best ways to promote real ecumenicalism among the Christian communions is to share one another’s saints (I draw the line at the popularly venerated Rasputin and Tsar Ivan the Terrible though . . . )
I’ve also written akathists in honour of the Anglican King Charles the Martyr (also used by Catholics who are converts from Anglicanism but who continue to venerated St Charles privately, as did Bl. Cardinal Newman) and also one to John Hus (for converts to Orthodoxy who come from the Hussite tradition and there are a few). The Czech Orthodox Church is now planning to formally canonize John Hus as an Orthodox saint (it is a long story, believe me) and they like my akathist to him . . .
