The 2002 Editio Typica Tertia of the Roman Missal includes a Votive Mass of the Mercy of God. The Collect for this new Mass formulary is derived in part from the oration that traditionally follows the Te Deum, and in part from the Collect of the Second Sunday of Pascha. The Prayer Over the Offerings contains, in the phrase, Christo iugiter confidentes, a subtle but unmistakable allusion to the invocation of Saint Faustina, “Jesus, I trust in you.” The Postcommunion expresses Saint Faustina’s two fold message: confidence in the mercy of God, and the practice of mercy toward one another.
God has loved us with an everlasting charity:
he sent his Only–begotten Son as the expiation for our sins,
and not for ours only
but also for the sins of the whole world (cf. Jer 31:3; 1 Jn 2:2).
The mercies of the Lord I will sing forever;
from generation to generation
my mouth will proclaim your truth (Ps 88:2).
