Editing Sanctification in Christianity (section)

===Reformed===
It is not clear that John Calvin, in his ''Institutes of the Christian Religion,'' conceives of sanctification as a doctrine separate from justification. There is no separate treatment there of a doctrine of sanctification. Instead, the clearest references he makes to the process of the Christian's growth in holiness appear in Book III of the Institutes, which concerns the work of the Holy Spirit. There he intermixes the grace by which justification is accomplished and the grace that empowers the Christian toward moral reform. Following Augustine, Calvin embraces a non-perfectionist account of sanctification as progressive but incomplete until eschatological consummation:<blockquote>"I insist not that the life of the Christian shall breathe nothing but the perfect Gospel, though this is to be desired, and ought to be attempted. I insist not so strictly on evangelical perfection, as to refuse to acknowledge as a Christian any man who has not attained it. In this way all would be excluded from the church, since there is no man who is not far removed from this perfection, while many, who have made but little progress, would be undeservedly rejected."<ref>(Institutes 3.6.5).</ref>  </blockquote>Against those who "maintain the perfection of holiness in the present life," Calvin replies:<blockquote>"...we deem it sufficient briefly to reply with Augustine, that the goal to which all the pious ought to aspire is, to appear in the presence of God without spot or blemish; but as the course of the present life is at best nothing more than progress, we shall never reach the goal until we have laid aside the body of sin, and been completely united to the Lord."<ref>(Institutes 3.17.15).</ref> </blockquote> But the imperfection of sanctification in this life is not, for Calvin, an excuse for slackness in the search thereof. The grace of justification is not separable from the grace that makes one perform good works and the grace that perfects what is deficient in the works of the regenerate:<blockquote>“Justification, moreover, we thus define: the sinner being admitted into communion with Christ is, for his sake, reconciled to God; when purged by his blood he obtains the remission of sins, and clothed with righteousness, just as if it were his own, stands secure before the judgment seat of heaven. Forgiveness of sins being previously given, the good works which follow have a value different from their merit, because whatever is imperfect in them is covered by the perfection of Christ, and all their blemishes and pollutions are wiped away by his purity, so as never to come under the cognizance of the divine tribunal. The guilt of all transgressions, by which men are prevented from offering God an acceptable service, being thus effaced, and the imperfection which is wont to sully even good works being buried, the good works which are done by believers are deemed righteous, or, which is the same thing, are imputed for righteousness.”<ref>(Institutes 3.17.8).</ref> </blockquote>
