The following is an excerpt from On the Grace of God on John Calvin’s understanding of “gratuitous” grace.
In the Christian tradition, there are many adjectives that have accompanied the word grace: amazing, free, scandalous, surprising, special, inexhaustible, incalculable, wondrous, mysterious, overflow- ing, abundant, irresistible, costly, extravagant, and more. My favorite is from John Calvin—”gratuitous” grace. Gratuitous is the idea of something being unwarranted or uncalled for. Though we yearn des- perately for grace, the beautiful extravagance of God’s love in Christ is utterly uncalled for. Gratuitous. In his Institutes of the Christian Religion, John Calvin writes: “We make the foundation of faith the gratuitous promise, because in it faith properly consists. . . . Faith begins with the promise, rests in it, and ends in it” (Institutes 3.2.24).
In Calvin’s theology, the knowledge of God the redeemer focuses on the “gratuitous promise” as the main theme of Scripture. The gratuitous promise in Christ is the substance of Scripture. The various terms denoting the gratuitous promise of God exist throughout Calvin’s writings in countless variations: “gratuitous mercy,” “gratuitous favor,” “gratuitous goodness,” “mere good pleasure,” and “gratuitous love” (Institutes 2.7.4; 2.16.2; 2.17.1; 3.21.5; 3.21.7; 3.31.7) These expressions are also found throughout his commentaries, especially his Commentary on Romans and Commentary on Genesis.
God loves you with gratuitous grace, the only kind there is. God’s grace is unconditioned and unconditional.
