Gaudete or Refreshment Sunday

The third Sunday in Advent is "Refreshment Sunday", also known as Gaudete Sunday, and this year it falls on 13th December. 

"The season of Advent originated as a fast of 40 days in preparation for Christmas, commencing on the day after the feast of Saint Martin (11 November), and was originally called Saint Martin's Lent, a name by which it was known as early as the fifth century. In the ninth century, the duration of Advent was reduced to four weeks (a period starting four Sundays before Christmas), and Advent preserved most of the characteristics of a penitential season, which made it a kind of counterpart to Lent. Gaudete Sunday is a counterpart to Laetare Sunday, and provides a similar break about midway through a season which is otherwise of a penitential character, and signifies the nearness of the Lord's coming." (Wikipedia) 

On Gaudete Sunday rose-coloured vestments may be worn instead of violet which is otherwise prescribed for every day in the season of Advent, and it is therefore also known as "Rose Sunday". Rose is the liturgical colour for joy. In churches that have an Advent wreath, the rose-coloured candle is lit in addition to two of the violet candles, which represent the first two Sundays of Advent. Despite the otherwise sombre readings of the season of Advent, which recognises the need for penitence in anticipation, the readings on the third Sunday emphasises the joyous anticipation of the Lord's coming.

Gaudete means “rejoice”. and it is a reminder that the Advent season is a season of joy because our salvation is already at hand. To have a Sunday of rejoicing in the midst of the traditional Advent fast is not simply a concession to human weakness. It serves to correct spiritual pride, reminding those who fast that the whole of the Christian life is a matter of grace. John the Baptist reminds us that salvation is a gift of grace, it is not bestowed on us in return for penitence. Joy is the experience of knowing that you are unconditionally loved, it requires no external conditions, unlike happiness. 

“Rejoice in the Lord always; again I say, rejoice. Indeed, the Lord is near.” Philippians 4:4-5

Advent is a time of watching, waiting and listening, remembering and anticipating, renewal and wonder. On Gaudete Sunday we should rejoice in the unconditional love of God, as we anticipate the fulfilment of his gift of love at Christmas.
