Gaudete Sunday, sometimes called Rejoice Sunday, is the mid-point during the Advent season. Advent is, like Lent, a penitential time but shortened considerably. During Advent priests wear purple and some aspects of the liturgy are, like Lent, not performed. Likewise, the altar is kept as simple as possible. On Gaudete Sunday, the priest will wear a rose or pink color vestment, flowers are allowed in the altar, and the use of an organ is allowed as well. The purpose of the day is to remind that during a time of penance (or any period of darkness) is that God’s joy is with us. That times of darkness are temporary, and we should rejoice. The Advent wreath candle for the day is also rose or pink as well. The word gaudete means rejoice in Latin.

The hymn Veni, veni, Emmanuel (or better known in English as (O come, O come, Emmanuel ) is sung in churches on this day.

Veni, Veni Emmanuel
Veni, veni Emmanuel!
Captivum solve Israel!
Qui gemit in exilio,
Privatus Dei Filio,
Gaude, gaude, Emmanuel
nascetur per te, Israel.

O come, O come, Emmanuel,
And ransom captive Israel,
That mourns in lonely exile here,
Until the Son of God appear.
Rejoice ! Rejoice ! Emmanuel
Shall come to thee, O Israel.
