Laetare Sunday (Church Latin: ; Classical Latin: ; English: ) is the fourth Sunday in the season of Lent, in the Western Christian liturgical calendar. Traditionally, this Sunday has been a day of celebration, within the austere period of Lent. This Sunday gets its name from the first few words () of the traditional Latin entrance (Introit) for the Mass of the day. ("Rejoice, O Jerusalem") is Latin from Isaiah 66:10. History The term "Laetare Sunday" is used by most Roman Catholic, Lutheran and Anglican churches. The word comes from the Latin , the singular imperative of : "to rejoice". The full Introit reads: Psalm: Rejoice ye with Jerusalem; and be ye glad for her, all ye that delight in her: exult and sing for joy with her, all ye that in sadness mourn for her; that ye may suck, and be satisfied with the breasts of her consolations. Psalm: I was glad when they said unto me, We will go into the house of the Lord. Alternative names This Sunday is currently also known as Mothering Sunday, Refreshment Sunday, mid-Lent Sunday (in French ) and Rose Sunday (either because the golden rose sent by Popes to Catholic sovereigns used to be blessed at this time, or because the use of rose-colored rather than violet vestments was permitted on this day). Historically, the day was also known as "the Sunday of the Five Loaves," from the story of the miracle of the loaves and fishes. Before the adoption of the modern "common lectionaries", this narrative was the traditional Gospel reading for this Sunday in Roman Catholic, Lutheran, Anglican, and Old Catholic churches. The station church at Rome for this day was Santa Croce in Gerusalemme, one of the seven chief basilicas; the Golden Rose, sent by Popes to Catholic sovereigns, used to be blessed at this time and for this reason the day was sometimes called Dominica de Rosa. Customs On Mothering Sunday, Christians have historically visited their mother church—the church in which they received the sacrament of baptism. In Roman Catholic, Anglican, Lutheran and Old Catholic churches flowers may appear on the high altar and the organ may be played as a solo instrument. Priests are given the option to wear rose-colored vestments at Mass held on this day in place of the violet vestments normally worn during Lent. The term "rose" is used to describe this lighter shade
