Information is from the Canon Regulars of St. John Cantius:
The Cross of Christ is veiled, so that we may seek it, and Him who died on it, all the more. The holiest season of the year is at hand, so holy, that "all other seasons of the year prepare us for keeping this one duly and worthily. These present days call for special fidelity seeing that they bring us so near to that sublime mystery of the Divine Mercy, the blessed Passion of Jesus Christ." (From the Divine Office)
With an open mind and a willing heart let us approach the altar to celebrate the Passion Sunday Sacrifice with our High Priest, so that His "body, which shall be delivered for us, and His blood that shall be shed for us" may bestow upon us the promise of eternal inheritance in Christ Jesus Our Lord.
Let us pray: Deliver me, O Lord, from my enemies. Teach me to do Thy will. Through Christ, Our Lord. Amen.
