Lord, true source of light and wisdom,
give me a keen sense of understanding, a retentive memory, and capacity to grasp things correctly.
Grant me the grace to be accurate in my expositions and the skill to express myself with thoroughness and clarity.
Be with me at the start of my work, guide its progress and bring it to completion.
Grant this through Christ, our Lord. AMEN.
Saint Thomas Aquinas, pray for us.
