I wonder how it is that priests and religious can say compline from memory. I can't do it. I know, you're going to say "But they use an invariable compline!" Well, thanks to the Consilium, so do I. I only use the compline from Sunday after II vespers, just like the pre-Pius X breviaries had. But even still, I remember everything but the psalm 'Qui habitat in audiutorio Altissimi' and the short reading. I guess that's okay, but I'm missing the most important part.
