Deus, in te sperántium fortitúdo, adésto propítius invocatiónibus nostris: et, quia sine te nihil potest mortális infírmitas, præsta auxílium grátiæ tuæ; ut, in exsequéndis mandátis tuis, et voluntáte tibi et actióne placeámus.
O God, the Strength of all them that put their trust in thee, mercifully accept our prayers, and because through the weakness of our mortal nature we can do no good thing without thee, grant us the help of thy grace, that in keeping of thy commandments we may please thee, both in will and deed.
