Today is the seven hundredth anniversary of the canonization of St. Thomas Aquinas. From his commentary on the letter of Paul to the Ephesians:
The faithful must be strong through charity, for love is as strong as death (Song 8:6); hence, it is symbolized by a pillar of fire capable of consuming everything: therefore, they received a burning pillar of fire for a guide on the unknown journey (Wis 18:3). As fire makes the surroundings visible, puts metals to the test, and destroys what can burn, so charity enlightens human actions, examines one's motives, and exterminates all vices.
