From St. Thomas Aquinas
O Lord my God, help me to be obedient without reserve, poor without servility, chaste without compromise, humble without pretense, joyful without depravity, serious without affectation, active without frivolity, submissive without bitterness, truthful without duplicity, fruitful in good works without presumption, quick to revive my neighbor without haughtiness, and quick to edify others by word and example without simulation.
Grant me, 0 Lord, an ever-watchful heart that no alien thought can lure away from you; a noble heart that no base love can sully; an upright heart that no perverse intention can lead astray; an invincible heart that no distress can overcome; an unfettered heart that no impetuous desires can enchain.
O Lord my God, also bestow upon me understanding to know you, zeal to seek you, wisdom to find you, a life that is pleasing to you, unshakable perseverance, and a hope that will one day take hold of you. May I do penance here below and patiently bear your chastisements. May I also receive the benefits of your grace, in order to taste your heavenly joys and contemplate your glory.
Amen.
