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).
Or:
The mercies of the Lord I will sing forever;
from generation to generation
my mouth will proclaim your truth (Ps 88:2).

O God, Who under a wonderful Sacrament, hast left unto us whereby to show forth Thy Suffering Death, grant unto us, we beseech Thee, so reverently to handle the Sacred Mysteries of Thy Body and Thy Blood that we may always feel within ourselves the fruit of Thy Redeeming Work. Who livest and reignest with God the Father, in the unity of the Holy Ghost, one God, world without end. (Translation of the Collect of Corpus Christi by the Marquess of Bute)

Already in the mystical invasion of 17th century France, Catherine de Bar (Mère Mechthilde du Saint–Sacrement, 1614–1698), foundress of the Benedictines of the Most Holy Sacrament, initiated a weekly rememoration of both Maundy Thursday and the festival of Corpus Christi. Whenever the rubrics allowed, Thursdays were marked by a Votive Mass and Office of the Most Holy Eucharist and by adoration of the Blessed Sacrament exposed in the monstrance, a rare privilege at the time. The Cistercians too marked Thursdays in the same way; Cistercian liturgical books contain a Votive Office of the Blessed Sacrament.

During the Year of the Eucharist, I proposed a weekly Votive
