“…What you probably have not heard is that the JDDJ very carefully avoid precise definitions of the words grace, faith, sin, etc. That is no accident. Careful definition of those terms would have shown how far apart our two churches actually are on the doctrine of justification…”
Precise definitions from the
glossary of the CCC:
**FAITH: **Both a gift of God and a human act by which the believer gives personal adherence to God who invites his response, and freely assents to the whole truth that God has revealed. It is this revelation of God which the Church proposes for our belief, and which we profess in the Creed, celebrate in the sacraments, live by right conduct that fulfills the twofold commandment of charity (as specified in the ten commandments), and respond to in our prayer of faith. Faith is both a theological virtue given by God as grace, and an obligation which flows from the first commandment of God (26, 142, 150, 1814, 2087).
**GRACE: **The free and undeserved gift that God gives us to respond to our vocation to become his adopted children. As sanctifying grace, God shares his divine life and friendship with us in a habitual gift, a stable and supernatural disposition that enables the soul to live with God, to act by his love. As actual grace, God gives us the help to conform our lives to his will. Sacramental grace and special graces (charisms, the grace of one’s state of life) are gifts of the Holy Spirit to help us live out our Christian vocation (1996, 2000; cf. 654).
**SIN: **An offense against God as well as a fault against reason, truth, and right conscience. Sin is a deliberate thought, word, deed, or omission contrary to the eternal law of God. In judging the gravity of sin, it is customary to distinguish between mortal and venial sins (1849, 1853, 1854).
And, for good measure:
**JUSTIFICATION: **The gracious action of God which frees us from sin and communicates “the righteousness of God through faith in Jesus Christ” (
Rom 3:22). Justification is not only the remission of sins, but also the sanctification and renewal of the interior man (1987-1989).
**SALVATION: **The forgiveness of sins and restoration of friendship with God, which can be done by God alone (169).
**SANCTIFYING GRACE: **The grace which heals our human nature wounded by sin by giving us a share in the divine life of the Trinity. It is a habitual, supernatural gift which continues the work of sanctifying us–of making us “perfect,” holy, and Christlike (1999).
