We call this week Holy Week.
It begins today with the celebration of Palm Sunday, where we enter into the presence of Christ's triumphal entry into Jerusalem at the approach of His hour. The latter part of the Holy Week is known as the Easter Triduum, which includes Holy Thursday and the celebration of the Last Supper as we rejoice in the Eucharist and the priesthood, and Good Friday with the Passion and death of our Lord.
The Easter Triduum concludes with the celebration of Easter with the Vigil in the night and with the Masses throughout Easter Sunday. May this be a week where we grow in holiness as we accompany the Son of God through his passion, death and Resurrection.
May God Bless you.
