[Heb. 11:6], and, "Be of good faith, son, thy sins are forgiven thee" [Matt. 9:2; Mark 2:5], and, "The fear of the Lord driveth out sin" [Eccles. 1:27], and, "Do penance, and be baptized every one of you in the name of Jesus Christ for the remission of your sins, and you shall receive the Holy Spirit" [Acts 2:38], and, "Going therefore teach all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things whatsoever I have commanded you" [Matt. 28:19], and finally, "Prepare your hearts unto the Lord" [I Kings 7:3].

Chap. 7. In What the Justification of the Sinner Consists, and What are its Causes

799. Justification itself follows this disposition or preparation, which is not merely remission of sins [can. 11], but also the sanctification and renewal of the interior man through the voluntary reception of the grace and gifts, whereby an unjust man becomes a just man, and from being an enemy becomes a friend, that he may be "an heir according to hope of life everlasting" [Tit. 3:7]. The causes of this justification are: the final cause indeed is the glory of God and of Christ and life eternal; the efficient cause is truly a merciful God who gratuitously "washes and sanctifies" [I Cor. 6:11], "signing and anointing with the Holy Spirit of promise, who is the pledge of our inheritance" [Eph. 1:13 f.]; but the meritorious cause is His most beloved only-begotten Son, our Lord Jesus Christ, "who when we were enemies" [cf. Rom. 5:10], "for the exceeding charity wherewith he loved us" [Eph. 2:4], merited justification for us [can. 10] by His most holy passion on the wood of the Cross, and made satisfaction for us to God the Father; the instrumental cause is the sacrament of baptism, which is the "sacrament of faith," ¹ without which no one is ever justified. Finally the unique formal cause is the "justice of God, not that by which He Himself is just, but by which He makes us just" ² [can. 10 and 11], that, namely, by which, when we are endowed with it by him, we are renewed in the spirit of our mind, and not only are we reputed, but we are truly called and are just, receiving justice within us, each one according to his own measure, which the "Holy Spirit distributes to everyone as he wills" [I Cor. 12:11], and according to each one's own disposition and cooperation.

800. For although no one can be just but he to whom the merits of the passion of our Lord Jesus Christ are communicated, yet this does take place in this justification of the ungodly when by the merit of that same most holy passion "the charity of God is poured forth by the Holy Spirit
