Vespers for Saturday always anticipates the readings for Sunday. The Podcast for tonight’s vespers can be found here. The hymn is “Let All Mortal Flesh Keep Silence” and the talk at the end talks about that vulnerable part of ourselves most tripped over in silence.
Honestly, I don’t know how folks listen to the talking part of the podcast; it’s ants-in-the-pants for me.
The Benedictine Nuns at St. Walburga’s have an Advent reflection
The Dominican Nuns at Summit have posted an mp3 of their hymn for Vespers
Also, here again is the breviary I’m using – my favorite.
