John Calvin quotes, checked against the source

11 quotes · Checked October 2026

In brief

Calvin quotes travel well and often arrive without a reference. Here are 11 of the most shared, each checked against a public-domain edition: Henry Beveridge’s 1845 Institutes, the Calvin Translation Society’s commentaries, and Calvin’s tracts and letters. 7 are real or close to it, 1 is stitched together from 2 passages, 2 belong to other people, and 1 has a historian’s citation we haven’t been able to check yet. Where a quote is real, the original wording and the exact reference are below it.

How to read this page

“Real” means the sentence appears in the cited edition in that form or close to it. “Paraphrase” means the idea is his and the wording isn’t. “Not yet checked” means a credible writer gives a source that we haven’t been able to read ourselves; many of his sermons have no free English edition. If you know a better source for any of these, send a correction.

The quotes

1. “True wisdom consists in two things: knowledge of God and knowledge of self.”

Paraphrase of a real line. It is the opening sentence of the Institutes, tightened for a graphic.

Our wisdom, in so far as it ought to be deemed true and solid Wisdom, consists almost entirely of two parts: the knowledge of God and of ourselves.

Institutes 1.1.11

2. “The human heart is an idol factory.”

Real idea, modern wording. Beveridge’s 1845 translation has “mind” and “forge.” The word “factory” comes from a 20th-century translation.

Hence we may infer, that the human mind is, so to speak, a perpetual forge of idols.

Institutes 1.11.82

3. “Even a dog barks when his master is attacked. I would be a coward if I saw that God’s truth is attacked and yet would remain silent.”

Real in substance; the second sentence is a paraphrase. Calvin wrote the dog line to Marguerite, queen of Navarre, and used the image again in The Necessity of Reforming the Church (1543). The historian Philip Schaff quotes the letter this way:

Even a dog barks when his master is attacked; how could I be silent when the honor of my Lord is assailed?

Letter to the queen of Navarre, quoted in Schaff, History of the Christian Church, vol. 8, section 1183

4. “While all men seek after happiness, scarcely one in a hundred looks for it from God.”

Stitched together. The first half comes from Calvin’s commentary on Psalm 1:1, the second from his commentary on Psalm 119:1. They are 118 psalms apart.

For while all men naturally desire and seek after happiness, we see how securely they can indulge themselves in their sins.

Commentary on the Psalms, on Psalm 1:14

And the further a man wanders from God, the happier does he imagine himself to be; and hence all treat, as a fable, what the Holy Spirit declares about true piety and the service of God. This is a doctrine which scarcely one among a hundred receives.

Commentary on the Psalms, on Psalm 119:15

5. “There is not one blade of grass, there is no color in this world that is not intended to make us rejoice.”

Cited by a historian; not yet checked by us. Quote sites usually place it in the Psalms commentary, on Psalm 104, and it isn’t there. The nearest passage, on Psalm 104:15, says wine was given “to make us merry,” tempered with sobriety. The quote is usually traced to William Bouwsma’s 1988 biography John Calvin: A Sixteenth-Century Portrait (pp. 134-35), which cites Calvin’s tenth sermon on 1 Corinthians. That sermon was preached in French and has no free English edition, and we haven’t yet seen Bouwsma’s page or the French ourselves.6

6. “We are all beggars.”

Luther, not Calvin. “We are beggars. This is true” was found on a slip of paper on Martin Luther’s desk after he died in February 1546. Quote sites list it under Calvin because both were reformers.7

7. “God’s will is our peace.”

Dante, not Calvin. The line is spoken by Piccarda in the Paradiso, canto 3, about 250 years before Calvin. In Longfellow’s translation: “And his will is our peace.”8

8. “Prayer is the chief exercise of faith.”

Real. It’s word for word from his commentary on Daniel 9:1-3, where Daniel turns to prayer. People often look for it in the Institutes, whose chapter on prayer (3.20) has a similar title in Beveridge’s translation: “a perpetual exercise of faith.”

For what benefit do God’s promises confer on us, unless we embrace them by faith? But prayer is the chief exercise of faith.

Commentary on Daniel, on Daniel 9:1-39

9. “My heart I offer to you, Lord, promptly and sincerely.”

Real as his emblem; the words are attested after his death. Calvin sealed his letters with a hand holding out a heart from the 1540s, during his second stay in Geneva. The words “prompte et sincere” first appear with the image on a portrait made in 1566, 2 years after he died. The full Latin motto, “Cor meum tibi offero, Domine, prompte et sincere,” is how the emblem is usually read today. It’s a motto rather than a line from a book, which is why it never comes with a page number.10

10. “Knowledge of the sciences is only smoke apart from the heavenly science of Christ.”

Real, lightly reworded. From his commentary on 1 Corinthians 1:20, where Paul asks, “Where is the wise?”

We must carefully notice these two things, that a knowledge of all the sciences is mere smoke, where the heavenly science of Christ is wanting; and man, with all his acuteness, is as stupid for obtaining of himself a knowledge of the mysteries of God, as an ass is unqualified for understanding musical harmonies.

Commentary on 1 Corinthians, on 1 Corinthians 1:2011

11. “Seeing that a Pilot steers the ship in which we sail, who will never allow us to perish even in the midst of shipwrecks, there is no reason why our minds should be overwhelmed with fear and overcome with weariness.”

Real. It’s from a letter to his friend Guillaume Farel, written from Geneva on August 20, 1553. The same letter goes on to tell Farel that Michael Servetus had been recognized in Geneva and that Calvin had him detained.

It is as you say, my dear Farel. Although we may be severely buffeted hither and thither by many tempests, yet, seeing that a pilot steers the ship in which we sail, who will never allow us to perish even in the midst of shipwrecks, there is no reason why our minds should be overwhelmed with fear and overcome with weariness.

Letter to Farel, August 20, 155312

How to check a Calvin quote yourself

Most of Calvin in English is free and searchable.

  • The Institutes: Beveridge’s 1845 translation at CCEL. References look like 3.20.1: book, chapter, section.
  • The commentaries: the Calvin Translation Society’s 1840s and 1850s volumes at CCEL, and page by page at the Internet Archive.
  • Tracts and letters: Tracts Relating to the Reformation and Jules Bonnet’s Letters of John Calvin at the Internet Archive.
  • The Latin and French originals: the Calvini Opera (1863-1900), free at several libraries. Schaff’s footnotes often give the volume and column.

A quote with no book, chapter, or verse attached is a quote nobody has checked. Search a distinctive phrase at CCEL first, then in his letters. We missed the sources for three of the quotes above on our first pass because we looked only where they were rumored to be.

Corrections

  • October 2026 A re-check found sources we had missed for three quotes. “Prayer is the chief exercise of faith” is word for word in the Daniel commentary (we had called it a reworded chapter title). The “pilot steers the ship” line is from a 1553 letter to Farel (we had listed it as not found). The “blade of grass” line has a historian’s citation to a French sermon (we had listed it as not found).
