The Triduum Begins Written by Sister Therese Ann Rich in 2014 Our Chapel, ready for Holy Thursday Mass The Triduum, beginning with the liturgy on the evening of Holy Thursday and ending with evening prayer on Easter Sunday, is the church’s most sacred trifecta — after the Trinity, of course! These moments are part of the one paschal celebration in which we, along with all of creation, journey with Christ through passion, death, burial and resurrection. As you move from the joyous beginning of Holy Thursday into the quiet stillness of evening, take time to gather your own joys and struggles — and those of the rest of the world — and walk closely with Christ.
