John Calvin on the Gospel

(Quotes taken from Calvin's Institutes of the Christian Religion)

“By the Gospel, I understand the clear manifestation of the mystery of Christ. I confess, indeed, that inasmuch as the term Gospel is applied by Paul to the doctrine of faith (1 Tim. 4:6), it includes all the promises by which God reconciles men to himself, and which occur throughout the Law. For Paul there opposes faith to those terrors which vex and torment the conscience when salvation is sought by means of works. Hence it follows that Gospel, taken in a large sense, comprehends the evidences of mercy and paternal favor which God bestowed on the Patriarchs. Still, by way of excellence, it is applied to the promulgation of the grace manifested in Christ.” (2.9.2)

“Paul, after calling the Gospel “the power of God unto salvation to every one that believeth,” shortly after adds, that it was “witnessed by the Law and the Prophets,” (Rom. 1:16; 3:21). And in the end of the same Epistle, though he describes “the preaching of Jesus Christ” as “the revelation of the mystery which was kept secret since the world began,” he modifies the expression by adding, that it is “now made manifest” “by the scriptures of the prophets,” (Rom. 16:25, 26). Hence we infer, that when the whole Law is spoken of, the Gospel differs from it only in respect of clearness of manifestation.” (2.9.4)

“The sum of the Gospel is, not without good reason, made to consist in repentance and forgiveness of sins; and, therefore, where these two heads are omitted, any discussion concerning faith will be meager and defective, and indeed almost useless.” (3.3.1)

“Hence Paul designates faith as the obedience which is given to the Gospel (Rom. 1:5); and writing to the Philippians, he commends them for the obedience of faith (Phil. 2:17). For faith includes not merely the knowledge that God is, but also, nay chiefly, a perception of his will toward us.” (3.2.6)

“Moreover if it is true, and nothing can be more certain, than that a complete summary of the Gospel is included under these two heads—viz. repentance and the remission of sins, do we not see that the Lord justifies his people freely, and at the same time renews them to true holiness by the sanctification of his Spirit?” (3.3.19)
