The third Sunday in Advent is also known as Gaudete Sunday. The name Gaudete comes from the Latin introit for the third Sunday in Advent.

Traditionally the Advent candle and vestments for Gaudete Sunday are rose coloured, rather than the violet of Advent.  (You may have noticed Liz was wearing a rose-coloured stole this morning.)  In the photo above the Choristers of Wellington Cathedral light the rose-coloured candle for the third Sunday in Advent.
