Note

“These three events in our Lord’s life—the Last Supper, the crucifixion and the resurrection—form a single redemptive act, which we call the Paschal Mystery. In the same way, ‘Though chronologically three days,’ the three days of the Paschal Triduum ‘are liturgically one day unfolding for us the unity of Christ’s Paschal Mystery.’ Likewise, the Mass of the Lord’s Supper on Holy Thursday, the Liturgy of the Lord’s Passion on Good Friday, and the Easter Vigil Mass form in a way a single, extended liturgical celebration, not three different liturgies.”
