Q. 1. What does the word "Passiontide" mean?

A. 1. Passiontide, in the Christian liturgical year, is the name of the last two weeks of Lent, beginning on the Fifth Sunday of Lent, long celebrated as Passion Sunday, and ending on Holy Saturday.

During this time, crucifixes, images, statues, icons and paintings are veiled in violet shrouds, the color of vestments during Lent, starting on Passion Sunday: "The practice of covering crosses and images in the church may be observed, if the episcopal conference decides. The crosses are to be covered until the end of the celebration of the Lord's passion on Good Friday. Statues and images are to remain covered until the beginning of the Easter Vigil." (Specifically, those veils are removed during the singing of the Gloria.) The veiling was associated with Passion Sunday's Gospel (John 8:46-59), in which Jesus "hid himself" from the people.

In the Tridentine Mass, Psalm 42 (43) is omitted at ferial Masses until Holy Thursday inclusive, as is the short doxology (Gloria Patri) at the Introit and the Psalm Lavabo at Mass. It is likewise omitted in Psalm 94 at Matins, and the responds at Matins, Prime, Terce, Sext, None, and Compline. Also in the ferial Mass, the Preface for Lent gives way to the Preface of the Cross.

Even though the last two weeks before Easter are no longer officially called Passiontide, the tradition is still practiced in many places.
