Just so I don't forget...
Translations for common Latin/Greek phrases. My vocab. is awful but my grammar is okay.
avito viret honore: He flourishes on the honors of his ancestors. Interesting.
laborare est orare: Work is prayer. I don't know the original context of this one, but I wonder if something similar could be said of making music for the liturgy...
peccare/peccatoribus: To err, sin. So that's what it means!
