I had attended a few services at the OCA parish near me, and there was a portion of the Liturgy where they dismissed catechumens. "All catechumens, depart. Let no catechumen remain."
Well, that parish was not holding Liturgy today because they were ordaining a priest in Rochester, so I went back to the Greek church that I love, but don't understand, and I had forgotten about this--they don't say that in their Liturgy. Is it a difference in Liturgical processes between the jurisdictions? Do they not do that if the parish doesn't have any catechumens at the time? That would be less likely--this is a much larger parish.
One misconception I had going in was, I assumed all Orthodox churches observed the same Liturgy, but that could be my RC "Where's my missal?" syndrome, because there are small differences between the services at the Greek church and the OCA, but I was curious about this one difference. I think it's mostly because I don't understand why catechumens would be dismissed for part of a Liturgy, whereas I'm a bumpkin off the street and can stay for the whole thing, but when the Greek church didn't do that at all, that had me wondering.
So I have two questions: 1) Why would one Orthodox church dismiss catechumens and another one not dismiss, and 2) Why dismiss them at all?
