Question from Marge on 3/22/2008:
When does Lent end? I've heard different answers to this question.
Answer by Catholic Answers on 3/24/2008:
Lent ends when the Mass of the Lord's Supper on Holy Thursday begins because that Mass ushers in the Triduum, which is a liturgical season in its own right:
With the celebration of Mass on the evening of Holy Thursday, "the Church begins the Easter Triduum and recalls the Last Supper in which the Lord Jesus, on the night he was betrayed, showing his love for those who were his own in the world, he gave his body and blood under the species of bread and wine offering to his Father and giving them to the Apostles so that they might partake of them, and he commanded them and their successors in the priesthood to perpetuate this offering" (Paschale Solemnitatis 44, emphasis added).
