PRAYERS: Triduum Prayers at Our Lady of Mt. Carmel's Parish
The schedule of Triduum prayers at Our lady of Mt. Carmel's parish are regularly posted at the weekly parish bulletins and on the parish web and social sites online.
The word "triduum" comes from the Latin word triduum, which comes from tris (“three”) + dies (“day”).
Sundown on Holy Thursday to sundown on Easter Sunday is considered the most solemn part of the liturgical year. This three-day period is referred to as the Easter Triduum, also known as the Sacred Triduum, or Paschal Triduum.
Basically, the Sacred Triduum is one great festival recounting the last three days of Jesus' life on earth, the events of his Passion and Resurrection, when the Lamb of God laid down his life in atonement for our sins.
"Though chronologically three days, they are liturgically one day unfolding for us the unity of Christ's Paschal Mystery."
(USCCB).
