Prayer before the Divine Office

O Lord, open Thou my mouth that I may bless Thy Holy Name;

cleanse my heart from all vain, evil, and wandering thoughts;

enlighten my understanding;

kindle my affections, that I may worthily, attentively,

and devoutly recite this office,

and may deserve to be heard before

the presence of Thy divine Majesty.

Through Christ our Lord.

Amen.
