In the area south of the Pantheon you can find several stores selling ecclesiastical items, ranging from miters and red socks to vestments and chalices. Rose vestments have been featured in the store windows for the last couple of weeks.
This Sunday is Gaudete Sunday, the third Sunday of Advent. "Gaudete" comes from the Latin Antiphon, which begins, "Gaudete in Domino semper: iterum dico, gaudete.." [Rejoice in the Lord always, again I say, rejoice...]. On this day, rose-colored vestments are worn, the rose candle in the Advent Wreath is lit and flowers may decorate the chancel of the church. (Latare Sunday in Lent is the only other day that rose vestments are worn.)
