I haven't posted for a bit simply because Rachel's been up & I've been posting stuff for Advent elsewhere (https://lovebloomsbright.wordpress.com). However, Advent 3 is Gaudete Sunday, which takes its name from the Latin word Gaudete ("Rejoice"), the first word of the introit in the Mass Propers for Advent 3:
Gaudete in Domino semper: iterum dico, gaudete. Modestia vestra nota sit omnibus hominibus: Dominus enim prope est. Nihil solliciti sitis: sed in omni oratione petitiones vestræ innotescant apud Deum. Benedixisti Domine terram tuam: avertisti captivitatem Jacob.
"Rejoice in the Lord always; again I say, rejoice. Let your forbearance be known to all, for the Lord is near at hand; have no anxiety about anything, but in all things, by prayer and supplication, with thanksgiving, let your requests be known to God. Lord, you have blessed your land; you have turned away the captivity of Jacob.".
It's one of the two Sundays in the year when rose-coloured vestments may be worn instead of violet, (or Sarum blue if you're Very Percy Dearmer!).
Rejoicing and thanksgiving are vital parts of the life of faith: without them, life descends into an unremmitting grind of trying (and generally failing) to "do the right thing". If Christians ain't joyful, then we are very unlikely to convince anyone that the our faith is life enhancing rather than life inhibiting. And if we can't do that, we're failing in our commission to go out and preach the GOOD News!
Smile! It's Gaudete Sunday!
