Christopher has been doing some good thinking recently on the Daily Office (and also here) and it’s place in our daily life. His conclusion is that Cranmer’s twice-daily Office should be seen as an ideal. Fr. Chris agrees and sees additional offices as a calling for some but not necessarily the ideal for all.
I quite agree with them both. I always fight a more-is-better tendency when it comes to the liturgy in general and the Office in particular. But, in the interests of both predictablity and sustainability sometimes we—ok, I—need to remember and relapse into what Christopher calls “Benedictine simplicity done elegantly”.
