All the arts come from God and are to be respected as divine inventions

The human heart is a factory of idols...Everyon e of us is, from his mother's womb, expert in inventing idols.

Things that are seen are temporal; things that are unseen are eternal.

Now the great thing is this: we are consecrated and dedicated to God in order that we may thereafter think, speak, meditate, and do, nothing except to his glory. For a sacred thing may not be applied to profane uses without marked injury to him.

It would be the height of absurdity to label ignorance tempered by humility "faith"! (Institutio III.2.3)

That man is truly humble who neither claims any personal merit in the sight of God, nor proudly despises brethren, or aims at being thought superior to them, but reckons it enough that he is one of the members of Christ, and desires nothing more than that the Head alone should be exalted.

So great and boundless is God's wisdom that he knows right well how to use evil instruments to do good.
