Lastly, some people do not pray it because they say they do not have the time. I find this hard to believe that anyone can not fit in one Hour, in some modified shape or form, into their lives.
Indeed, if simply reading the LOTH, without singing, even the major hours shouldn’t take more than 10 minutes if you’re rushed. If you’re not rushed, you can take more time, silences between psalms/after readings, etc. The minor hours even less. The Office of Readings is perhaps the longest. The beauty of the Office is that you can make it take as little time as you need, or as much time as you want. Even when I was commuting 100 km to work each day, I somehow managed to
chant Lauds, Vespers and Compline, and read the OOR and mid-day prayer. With the LOTH, chanted Lauds or Vespers would take 20 minutes tops, 25 if I dragged it out. I use Les Heures Grégoriennes when doing the (non-monastic) LOTH, to chant it.
There have been various points in history, even pre-Vatican II, where parishes in some countries did have Matins or Vespers offered publicly, usually on Sundays and major feasts.
And there is the paradox. When the Office was long, sung, and in Latin, the laity could be exposed to it quite frequently in many places. Now that it is
recommended for the laity and has been made shorter and more manageable, good luck finding a parish where it is prayed in public. There are a few places here and there, and if you live in a large enough city there are religious communities that pray it and allow the public to attend. And this, even though the Church
especially recommends the public celebration of Vespers on just the occasions you note. I actually think Vespers in the LOTH is
too short for public celebration. It hardly seems worth one’s while to trudge to the local church for a 20-minute Office. Perhaps the Church should encourage borrowing from tradition by using Monastic sung Vespers on Sundays. It would be the same psalms every Sunday (109, 110, 111, 112 in the Vulgate numbering) so eventually folks would become familiar with the tones and there would still be some variety (seasonal Magnificat antiphons and different ones for feasts as well). Such an Office is usually about 35 minutes in a monastery, maybe 40 if incense is used and the solemn Magnificat tones used.
I doubt if there hadn’t been a monastery nearby, that I would have discovered it, since it flies so low under the radar in most places. Pity.
