Joint Declaration on the Doctrine of Justification
3. The Common Understanding of Justification
...
15.In faith we together hold the conviction that justification is the work of the triune God. The Father sent his Son into the world to save sinners. The foundation and presupposition of justification is the incarnation, death, and resurrection of Christ. Justification thus means that Christ himself is our righteousness, in which we share through the Holy Spirit in accord with the will of the Father. Together we confess:
By grace alone, in faith in Christ's saving work and not because of any merit on our part, we are accepted by God and receive the Holy Spirit, who renews our hearts while equipping and calling us to good works.

The Good Works of the Justified
...
38.According to Catholic understanding, good works, made possible by grace and the working of the Holy Spirit, contribute to growth in grace, so that the righteousness that comes from God is preserved and communion with Christ is deepened. When Catholics affirm the "meritorious" character of good works, they wish to say that, according to the biblical witness, a reward in heaven is promised to these works. Their intention is to emphasize the responsibility of persons for their actions, not to contest the character of those works as gifts, or far less to deny that justification always remains the unmerited gift of grace.
