At our small mission we do have our own priest, but we (chanters with the support of our parish council) ordered our priest to take this coming Sunday off. His wife is fighting pancreatic cancer and just before Christmas had surgery to repair a broken hip. She is recovering well and is in rehabilitation now. But we know how exhausted he is.
About once a year, we do a reader's service on Sunday mornings to give our priest a bit of a holiday. Though as you can see from what I've just written, we may do several this year.
Given that we are in rented quarters and have a limited number of people to assist, we rarely have Vespers, but on Sundays always have Orthros and Liturgy. So this week, we will have a reader's Orthros and Typika. Our instructions are to follow the basic pattern, but replace the litanies with 3, 12, or 40 Lord have mercys, and a few other minor changes as well, such as plain reading the Epistle and Gospel (omitting the Gospel in Orthros).
Interestingly, it's a way to get the congregation to Orthros which is sadly attended. The reader's Orthros and Typika as we do them take 75-90 minutes together, about that of the DL, so we begin Orthros at the usual time for starting the DL.
