(cue fanfare) The Paschal Triduum:
99. On Holy Thursday at the evening Mass the remembrance of the meal preceding the Exodus casts its own special light because of the Christ’s example in washing the feet of his disciples and Paul’s account of the institution of the Christian Passover in the Eucharist.
On Good Friday the liturgical service has as its center John’s narrative of the Passion of him who was proclaimed in Isaiah as the Servant of the Lord and who became the one High Priest by offering himself to the Father.
At the Vigil on the holy night of Easter there are seven Old Testament readings which recall the wonderful works of God in the history of salvation. There are two New Testament readings, the announcement of the Resurrection according to one of the Synoptic Gospels and a reading from St. Paul on Christian baptism as the sacrament of Christ’s Resurrection.
The Gospel reading for the Mass on Easter day is from John on the finding of the empty tomb. There is also, however, the option to use the Gospel texts from the Easter Vigil or, when there is an evening Mass on Easter Sunday, to use the account in Luke of the Lord’s appearance to the disciples on the road to Emmaus. The first reading is from the Acts of the Apostles, which throughout the Easter season replaces the Old Testament reading. The reading from the Apostle Paul concerns the living out of the paschal mystery in the Church.
Which reminds me: you are planning to attend all the Triduum liturgies this year, especially the Easter Vigil, right?
