My friend Greg DiPippo posted something spectacular at NLM (he’s doing great work right now) about the Breviary.
Here is the quote, but you have to go there to find out more about it.
I close my eyes, and while my lips murmur the words of the Breviary which I know by heart, I leave behind their literal meaning, and feel that I am in that endless land where the Church, militant and pilgrim, passes, walking towards the promised fatherland. I breathe with the Church in the same light by day, the same darkness by night? I see on every side of me the forces of evil that beset and assail Her; I find myself in the midst of Her battles and victories, Her prayers of anguish and Her songs of triumph, in the midst of the oppression of prisoners, the groans of the dying, the rejoicing of the armies and captains victorious. I find myself in their midst, but not as a passive spectator; nay rather, as one whose vigilance and skill, whose strength and courage can bear a decisive weight on the outcome of the struggle between good and evil, and upon the eternal destinies of individual men and of the multitude.
