True wisdom consists in two things: Knowledge of God and Knowledge of Self.

The glory of God shines, indeed, in all creatures on high and below, but never more brightly than in the cross.

The more closely we see ourselves being watched by our enemies, the more time intent we should be to avoid their slanders.

We cannot rely on God's promises without obeying his commandments.

The evil in our desires typically does not lie in what we want, but that we want it too much.

Without Christ, sciences in every department are vain....The man who knows not God is vain, though he should be conversant with every branch of learning. Nay more, we may affirm this too with truth, that these choice gifts of God -- expertness of mind, acuteness of judgment, liberal sciences, and acquaintance with languages, are in a manner profaned in every instance in which they fall to the lot of wicked men.

Joy and thanksgiving expressed in prayer and praise according to the Word of God are the heart of the Church's worship.
