SS. Vitus, Modestus and Crescentia, Martyrs
Let us have recourse to St. Guy, to be preserved from the bite of mad dogs and from the sad disease which bears his name. He will obtain for us great docility towards the Holy Ghost, in order that we do good in all liberty, humility and charity (Collect).
Multae tribulationes justorum, et de his omnibus liberavit eos Dominus: Dominus custodit omnia ossa eorum: unum ex his non conteretur. * Benedicam Dominum in omni tempore: semper laus ejus in ore meo.
Many were the afflictions of the just, and out of all these the Lord hath delivered them: the Lord keepeth all their bones; not one of them shall be broken. * I will bless the Lord at all times: His praise shall be always in my mouth.
(Psalm 33:20-21,2 from the Introit of Mass)
Da Ecclesiae tuae, quaesumus, Domine, sanctis Martyribus tuis Vito, Modesto atque Crescentia intercedentibus, superbe non sapere, sed tibi placita humilitate proficere: ut, prava despiciens, quaecumque recta sunt, libera exerceat caritate.
Grant to Thy Church, we beseech Thee, O Lord, by the intercession of Thy holy martyrs, Vitus, Modestus and Crescentia, not to be proud-minded, but to make progress by humility pleasing unto Thee; that despising what is evil, she may exercise with an eager love the things which are right.
