I agree that the Orthodox (and Eastern Catholic) churches have much that's of value to all of us.
Kolokotronis persuaded me to attend a Greek Orthodox devotion last Lent. Lovely people over at St. Nektarios The Wonder Worker ... although I thought the roof would fall in when my daughter suggested that their liturgy needed an electric guitar!
I can spell "PAT" with my Greek alphabet blocks!
When I return to Civilization I'll have to attend one.
