Today is the Feast Day of St. Thomas Aquinas. At Catholic University, they used to cancel noon classes so the student body could attend Mass.
Below is a copy of one of my favorite prayers, authored by St. Thomas Aquinas himself and entitled Before Study. I found myself praying this often before writing a paper, speaking in public, or doing research.
Who, from the treasures of Your wisdom,
has established three hierarchies of angels,
has arrayed them in marvelous order
above the fiery heavens,
and has marshaled the regions
of the universe with such artful skill,
You are proclaimed
the true font of light and wisdom,
and the primal origin
raised high beyond all things.
Pour forth a ray of Your brightness
into the darkened places of my mind;
disperse from my soul
the twofold darkness
into which I was born:
sin and ignorance.
You make eloquent the tongues of infants.
Refine my speech
and pour forth upon my lips
the goodness of Your blessing.
Grant to me
keenness of mind,
capacity to remember,
skill in learning,
subtlety to interpret,
and eloquence in speech.
guide the beginning of my work,
direct its progress,
and bring it to completion.
You Who are true God and true Man,
Who live and reign, world without end.
