From the evening of Holy Thursday to the evening of Easter Sunday the church celebrates the Easter Triduum. Deriving its name from the Latin for “three days,” during this period of time we celebrate the passion, death, and resurrection of Jesus. During these days we perform actions which are unique in church- we wash feet, we kiss wood, kindle fires, and turn lights off and on. We listen to the stories of our salvation and with hearts converted by our Lenten discipline, we sing Alleluia to praise God for the tremendous mystery of his love. St. Augustine said, ‘We are an Easter people and Alleluia is our song.” Each day of the triduum has its own color- white for Holy Thursday and Holy Saturday, red for Good Friday.
The fifty days from Easter Sunday to Pentecost are celebrated in joy and exultation as one feast day, indeed as ‘one great Sunday’ (St. Athanasius). These are the days above all others when the Alleluia is sung! We live as if God’s Kingdom has come, for indeed, it has! The liturgical color is white.
