The 3rd Sunday of Advent is the Gaudete Sunday and a rose-coloured candle is lit on the advent wreath. (A proper advent wreath has 3 violet and one rose coloured candle)
Gaudete means “rejoice” …
When I looked for suitable music, I found this clip from last year. It’s the Christmas concert given by my little nephew’s school class and they sing – “Gaudete” as well as ” Joy to the world”…enjoy ( Philipp stands 4th from left in the front )
