Laetare Sunday is a popular name for the Fourth Sunday in Lent. The name comes from the first word of the Introit or entrance antiphon of the Mass for that day: In Latin, the entrance antiphon (Isaiah 66:10-11) begins “Laetare, Jerusalem” (“Rejoice, Jerusalem”). On the fourth Sunday of Lent, the fast practiced in Lent is allowed to be relaxed, hence the name “Refreshment Sunday.” In some churches the liturgical colors of the season are replaced with rose, hence the name “Rose Sunday.” In England apprentice boys got the day off to visit their mothers, hence this day was called “Mothering Sunday.”
