The priest at the church wants to do the LItia service at the Great Vespers on Nativity Eve following the Royal Hours. However, as this is a prescribed Vesperal Liturgy, I do not see how you can do this as Litia occurs before the Aposticha and there is no Aposticha at this Vespers. I think my priest just wants to do it because it's cool and doesn't really have a good sense for the typicon.
The only time I can find a Litia and Artoklasia is at Great Compline following the Little Doxology. But I'm pretty sure we're not doing that.
Am I correct in this?
