As St. Paul affirms, "Where sin increased, grace abounded all the more." But to do its work grace must uncover sin so as to convert our hearts and bestow on us "righteousness to eternal life through Jesus Christ our Lord." Like a physician who probes the wound before treating it, God, by his Word and by his Spirit, casts a living light on sin:
Conversion requires convincing of sin; it includes the interior judgment of conscience, and this, being a proof of the action of the Spirit of truth in man's inmost being, becomes at the same time the start of a new grant of grace and love: "Receive the Holy Spirit." Thus in this "convincing concerning sin" we discover a double gift: the gift of the truth of conscience and the gift of the certainty of redemption. The Spirit of truth is the Consoler.
MCITL 10th Anniversary: The Catechism and Scriptures together in the Sunday homily
"The integration of elements of the Catechism of the Catholic Church with the readings from the Lectionary offers us an opportunity to demonstrate how the Word of God is able to animate our personal and communal life with Christ and, at the same time, articulate the Church’s faith that has been immeasurably enriched by the living tradition of twenty centuries."-- Archbishop Donald Wuerl, intervention at the Synod of Bishops on the Word of God
