Prayer of Thanksgiving.

Prayer for a Votive Mass of Thanksgiving from the 1962 Missale Romanum

V. Dominus vobiscum.
R. Et cvm spiritu tuo.

Deus, cujus misericórdiæ
non est númerus
et bonitátis infinítus est
thesáurus: piíssimæ majestáti
tuæ pro collátis donis grátias
ágimus, tuam semper cleméntiam
exorántes; ut, qui peténtibus
postuláta concédis, eósdem non
déserens, ad prǽmia futúra dispónas.
Per Dóminum….

A LITERAL VERSION
O God, of whose mercy there is no reckoning,
and whose treasury of goodness is infinite:
always imploring Your clemency
we give thanks to Your most gracious Majesty for the gifts that have been conferred,
so that, You who grant the things petitioned to those seeking them,
even as You never abandon them,
may ready them for the rewards to come.

You will hear in this beautiful prayer an echo of Wisdom 7:14:

“For she [Wisdom] is an infinite treasure to men: which they that use, become the friends of God, being commended for the gifts of discipline….”
