Our Father (silently)
Hail Mary (silently)

. Blessed art Thou, O Lord, in the firmament of Heaven,
. And worthy to be praised, and glorious, and highly exalted forever.

Let us pray:
Almighty and everlasting God, Who hast granted Thy servants in the confession of the True Faith, to acknowledge the glory of an Eternal Trinity, and in the power of Thy majesty to adore a Unity: we beseech Thee that by the strength of this faith we may be defended from all adversity. Through Jesus Christ Our Lord.
