Holy Triduum

Easter Triduum, Holy Triduum, or Paschal Triduum is a term used by some Christian churches, particularly the Roman Catholic Church, the Lutheran Church, and many Anglicans, to denote, collectively, the three days from the evening of Holy Thursday (or Maundy Thursday) to the evening of Easter Sunday. The Triduum begins with the evening Mass of the Lord's Supper (or, where this is not celebrated, Vespers of Holy Thursday) and ends after Vespers at sunset on Easter Day. The term was used at the Second Vatican Council, when the revised liturgical calendar set the final part of Holy Week apart from Lent proper. Previously, these three days had already gained distinction from the rest of Holy Week with an observance of silence, which were also known as "the still days."During Mass, music was not to be played and all church bells were silenced. People were also encouraged to observe silence in their homes during this time. The tradition of silence and lack of music is continued in Vatican II practice.

Lord, by the suffering of Christ your Son you have saved us all from the death we inherited from sinful Adam. By the law of nature we have borne the likeness of his manhood. May the sanctifying power of grace help us to put on the likeness of our Lord in heaven who lives and reigns for ever and ever.
