When I was in college, one of the things I enjoyed doing at the Catholic student center was praying liturgy of the hours morning and evening prayer with other students and the priests. Now I live in a different city, and I did a Google search for churches that pray vespers. There is only one in my area that does this (both in the mornings and evenings) and it is within walking distance from my house. But it isn’t a Catholic Church, it is Eastern Orthodox (Antiochian). I talked with the priest and he said I was more than welcome to join in prayer. What I am wondering is whether it is encouraged for a Roman Catholic to participate in vespers with the Eastern Orthodox in an Eastern Orthodox church? Especially if there aren’t any other churches around that do it.
