Second Sunday of Easter (Divine Mercy Sunday) - Year C
“At the sight of the Lord the disciples rejoiced.”
Paschal joy is not just that of a possible transfiguration: it is the joy of the new presence of the Risen Christ dispensing to His own the Holy Spirit, so that He may dwell with them. The Holy Spirit is given to the Church as the inexhaustible principle of her joy as the bride of the glorified Christ…
Thus the Spirit, who proceeds from the Father and the Son and is their living mutual love, is henceforth communicated to the People of the New Covenant, and to each soul ready for His secret action. He makes us His dwelling place: dulcis hospes animae. Together with Him, man's heart is inhabited by the Father and the Son. The Holy Spirit raises up therein a filial prayer that springs forth from the depths of the soul and is expressed in praise, thanksgiving, reparation and supplication. Then we can experience joy which is properly spiritual, the joy which is a fruit of the Holy Spirit (Gal 5:22)… Such a joy henceforth characterizes all the Christian virtues. The humble human joys in our lives, which are like seeds of a higher reality are transfigured. Here below this joy will always include to a certain extent the painful trial of a woman in travail and a certain apparent abandonment, like that of the orphan: tears and lamentation, while the world parades its gloating satisfaction. But the disciples' sadness, which is according to God and not according to the world, will be promptly changed into a spiritual joy that no one will be able to take away from them (Jn 16:20-22).
