Laetare Sunday is the fourth Sunday in the Lenten season. Since it is half way through Lent, it is a time to rejoice (Laetare means rejoice) and a time to understand about baptismal rebirth. Priests can elect to wear rose colored vestments on this Sunday. And the Gospel of John account of the blind man being healed is read. The Solemnity of St. Joseph, which is observed on March 19, will be moved to the following day should it be on Laetare Sunday.
