Conclusions
Having read all of the above, it is obvious that both capitalizatons are acceptable, depending on the style choice and the context. While Fishhead's proposal (Liturgy of the Hours (Catholic Church)) is appreciated, IMO it adds an unnecessary level of complication for sake "political correctness" (I have a fixed-wing aircraft in mind), and violates "Titles should be as simple as possible without being too general." clause of WP:NC(CN). This article is, rightly or wrongly, currently focused to the Catholic service and its current form. At the risk of being frivolous, I must say that I consider most of the discussion above as "Wikipedia hairsplitting of the month". Editors are kindly invited to amend the article with few sentences regarding the approaches to capitalization. 

Is it Murphy's law that I come to close RM discussions involving Espoo, or just a result of law of large numbers? I admit I wanted to walk away from this closing, but it would result in waste spending of another admin's time. In any case, I'm switching back into "busy in real life" mode so, please, direct any further continuation, if called for, here, rather than on my talk page. ►
