Stir up your power, O Lord, and with great might come among us; and, because we are sorely hindered by our sins, let your bountiful grace and mercy speedily help and deliver us; through Jesus Christ our Lord, to whom, with you and the Holy Spirit, be honor and glory, now and for ever. Amen.
This Sunday takes its traditional name - Gaudete Sunday - from the first word of the introit in the proper of the Latin Mass. The introit comes from the Epistle lesson appointed now for Advent 3 in Year C.
Philippians 4:4-6Its use in Advent springs from the words "The Lord is near."
Rejoice in the Lord always; again I will say, Rejoice. Let your gentleness be known to everyone. The Lord is near. Do not worry about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
You may hear the ancient Gregorian Introit sung (twice) on this YouTube video.
Even as John the Baptist calls us to turn our lives around and get right with God and one another, we rejoice for we are being called back to life and the Giver of life.
May you rejoice in the Lord. Always.
