Veiling Statues in Lent
"In the Dioceses of the United States, the practice of covering crosses and images throughout the church from [the Fifth Sunday of Lent] may be observed. Crosses remain covered until the end of the Celebration of the Lord's Passion on Good Friday, but images remain covered until the beginning of the Easter Vigil."
