I went to visit an Antiochian Orthodox - Western Rite church in my area this morning, and talked with the priest, Fr. Theodore, for a good 20 minutes. Long story short, he invited me to pray the Morning Prayer with him. I turned him down.
As a Catholic in communion with the Holy See, should I have? I definitely would go to Mass at my local Catholic Church, no contest there. But is there anything wrong with a Catholic attending Orthodox Matins?
