Thomas Aquinas

To bear with patience wrongs done to oneself is a mark of perfection, but to bear with patience wrongs done to someone else is a mark of imperfection and even of actual sin.

Better to illuminate than merely to shine

Better to illuminate than merely to shine, to deliver to others contemplated truths than merely to contemplate.

To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.
