Gaudete Sunday- The third Sunday in Advent
The third Sunday in Advent, so named from the opening word of the Introit in the Mass, “Gaudete” (Rejoice). When obtainable, rose-colored vestments are used, to symbolize the fact that the penitential observances of the season are suspended for the day in order to rejoice in the Redemption which is so near at hand.
Though each of those who are called have his own station in life, though the sons of the Church are separated from each other by the passage of the years, yet the entire body of the faithful, having a common origin in the baptismal font, are crucified together with Christ in His passion, are raised up in His resurrection, and in His ascension are placed with Him at the Father’s right hand — and so likewise are they all with Him born in this Nativity. For every believer, in whatever part of the world he may be, who is reborn in Christ, quits the evil path of his first origin, and by being born again is changed into a new man. For no longer is he considered as an offspring merely of an earthly father, but as belonging now to the seed of the Savior, who for this reason became the Son of man that we might have the power of becoming sons of God. – Pope Saint Leo the Great
