re:What does Gaudete mean?
the third sunday of Advent, the vestments are Pink, (not the somber deep purple) and its supposted to be a time of rejoying-- (as i recall, and this is a dim memory) the gospel message is about John the baptist, who proclaims that the saviour is coming... and it was the only sunday in advent that there was song.. (oh come, oh come Emmanual, and randsom captive israel..)

and as for suet, butchers ususally have it, and grocery store meat departments can get it easily by request. warmed, (melted) and mixed with bird seed, it can be shaped for pretty bird feeders.. (the cold air keeps it stiff enough out side..) and the birds like the extra calories from the fat in the winter.
(avoid sunflower seeds, the shell have a chemical that acts as a herbiside.. the will inhibit anything from germinating.) all the other seeds should be toasted for an hour in a 200 degree oven... or you'll get a nice crop of weeds where ever you bird feeder was hung.. (or cheat, and use rolled oats with suet... rolled oats won't germinate, they are cheap, and left overs can (sans suet) can be served for breakfast!
