"your loving commands"

"O God, who have taught us to chasten our bodies for the healing of our souls, enable us, we pray, to abstain from all sins, and strengthen our hearts to carry out your loving commands."

"Deus, qui ob animarum medelam castigare corpora praecepisti, concede, ut ab omnibus possimus abstinere peccatis, et corda nostra pietatis tuae valeant exercere mandata.  Per."

O God, who, for the sake of the cure of [our] souls, have advised [us] to restrain [our] bodies, grant that we may be able to abstain from all sins, and [that] our hearts may have the strength to carry out the mandates of your kindness.  Through.

     Concluding prayer for Monday in the Second Week of Lent, Liturgy of the hours.  This derives from a prayer in the early 8th-century Gelasian sacramentary (no. 173; Corpus orationum no. 1940; Bruylants, vol. 1, p. 25):

Deus, qui ob animarum medelam ieiunii devotione castigari corpora praecepisti, concede, ut corda nostra ita pietatis tuae valeant exercere mandata, quatenus ab omnibus possimus semper abstinere peccatis.
