The Easter festival brings the grace of holiness from heaven to men. Through the repeated celebration of the sacred mysteries they receive the spiritual nourishment of the sacraments. Fostered at the very heart of holy Church, the fellowship of one community worships the one God, adoring the triple name of his essential holiness, and together with the prophet sings the psalm which belongs to this yearly festival: This is the day the Lord has made; let us rejoice and be glad. And what is this day? It is the Lord Jesus Christ himself, the author of light, who brings the sunrise and the beginning of life, saying of himself: I am the light of day; whoever walks in daylight does not stumble. That is to say, whoever follows Christ in all things will come by this path to the throne of eternal light. Such was the prayer Christ made to the Father while he was still on earth: Father, I desire that where I am they also may be, those who have come to believe in me; and that as you are in me and I in you, so they may abide in us.
