PRAYERS FOR BEFORE STUDYING.

Prevent our actions, we beseech Thee, O Lord, by Thy inspiration, and follow them with Thy help: so that every prayer and work of ours may always begin from Thee, and through Thee, once started, be finished. Through Christ our Lord. Amen. original: "Actiones nostras..." a traditional Catholic collect

O God, from whom every good thing takes its beginning, and always progressing toward better things receives its increase: grant to our supplications, we beseech Thee, that what we attempt to begin for the praise of Thy name, may, by the eternal gift of Thy paternal wisdom, be brought to its completion. Through our Lord, etc.

Most merciful Father, pour into us through the merit of Jesus Christ Thy son, the grace of the Holy Spirit, by which our intellect may be more fully enlightened in the liberal arts: which we may be able to turn at some time to Thy divine honor and our own spiritual benefit. Through Christ our Lord. Amen.

O ineffable Creator, who from the treasures of Thy wisdom hast established nine Choirs of Angels, and hast placed them above the empyrean heaven in wonderful order, and hast most elegantly distributed the parts of the universe. Thou, I say, who art called the true source of light and wisdom and the supereminent principle, deign to pour upon the darkness of my intellect a ray of Thy brightness, removing from me the twofold darkness in which I was born, namely sin and ignorance. Thou, who makest eloquent the tongues of infants, instruct my tongue, and pour into my lips the grace of Thy blessing. Give me sharpness of understanding, capacity for retaining, subtlety of interpreting, facility in learning, and a copious grace of speaking; prepare my start, direct my progress, and complete my ending. Through Christ our Lord. Amen.
