The Symbol of the faith confesses the greatness of God's gifts to man in his work of creation, and even more in redemption and sanctification. What faith confesses, the sacraments communicate: by the sacraments of rebirth, Christians have become "children of God," "partakers of the divine nature." Coming to see in the faith their new dignity, Christians are called to lead henceforth a life "worthy of the gospel of Christ." They are made capable of doing so by the grace of Christ and the gifts of his Spirit, which they receive through the sacraments and through prayer.
