"For it is by grace you have been saved, through faith, and this is not from yourselves, it is the gift of God, not by works, so that no one can boast." (Ephesians 2:8-9)
You were dead in your transgressions and sins, following the ways of this world, gratifying the cravings of the sinful nature. Like the rest, you were by nature deserving of wrath. But because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions. It is by grace that we have been saved. God raised us up with Christ and seated us with him in the heavenly realms, so that in the coming ages he might show the incomparable riches of his grace. For it is by grace you have been saved, through faith, and this is not from yourselves, it is the gift of God, not by works, so that no one can boast. We are his workmanship, created in Christ Jesus to do good works which God prepared in advance for us to do.
The Catechism cites this as the definitive statement of the Catholic understanding of salvation: grace is entirely God's gift, received through faith, yet it produces good works as its fruit, not as its condition (CCC 1989). The works that follow are not the basis of salvation but its evidence. We are God's workmanship, his poem, made for works he has already prepared. The works are ours to do but God's to prepare.
Paul then addresses the Gentile readers directly: remember that formerly you were excluded from citizenship in Israel, foreigners to the covenants of the promise, without hope and without God in the world. But now in Christ Jesus you who once were far away have been brought near by the blood of Christ. For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility. His purpose was to create in himself one new humanity out of the two, thus making peace, and in one body to reconcile both to God through the cross. The Catechism calls the Church this new humanity, the community in which every human division is overcome in Christ, the one who has broken down every dividing wall (CCC 776).
Brothers and sisters, you are God's workmanship, his poem. The good works he has prepared for you today were prepared before the foundation of the world. They are waiting for you. You do not need to manufacture them or to strain for significance. Walk through this day attentively and you will find the prepared works where he has placed them, in the need you will encounter, the person you will meet, the moment that calls for exactly what you carry.
Lord God, rich in mercy, you made us alive when we were dead. By grace we have been saved, not by our works, so that no one can boast. We are your workmanship. Lead us into the good works you have prepared for us this day. Through Christ our Lord. Amen.
