Vague on Vespers?
It's your weekly change to ask any questions about praying the Divine Office. If I don't know the answer, I'll run to the General Instruction and find out. If it's not clear in the General Instruction, I'll hazard an opinion but clearly mark it as such.
Welcome readers who are visiting here from Fr. Z's blog. I do not use a pre-Vatican II breviary, thus I would not be able to answer questions related to it. Perhaps someone should start a blog like mine for those who do pray from the older breviary. I will soon post some a couple links for online older breviaries.
