For Steadfastness

Grant me, I beseech Thee, O merciful God, prudently to study, rightly to understand, and perfectly to fulfill that which is pleasing to Thee, to the praise and glory of Thy name.

Thou, O Christ, art the King of glory; Thou art the everlasting Son of the Father. Amen. --Thomas Aquinas

Grant me, I beseech Thee, almighty and most merciful God, fervently to desire, wisely to search out, and perfectly to fulfill, all that is well-pleasing unto Thee. Order Thou my worldly condition to the glory of Thy name; and, of all that Thou requirest me to do, grant me the knowledge, the desire, and the ability, that I may so fulfill it as I ought, and may my path to Thee, I pray, be safe, straightforward, and perfect to the end.

Give me, O Lord, a steadfast heart, which no unworthy affection may drag downwards; give me an unconquered heart, which no tribulation can wear out; give me an upright heart, which no unworthy purpose may tempt aside.

Bestow upon me also, O Lord my God, understanding to know Thee, diligence to seek Thee, wisdom to find Thee, and a faithfulness that may finally embrace Thee. Amen. --Thomas Aquinas
