“The word grace evidently implies that there is no antecedent merit. And in this way the apostle to the Romans appears to argue, when he says, 'And if by grace, then is it no more of works: otherwise grace is no more grace. Now to him that worketh is the reward not reckoned of grace, but of debt.' All this is perfectly intelligible, even in the conduct of liberal and magnificent human characters. They frequently bestow their gifts from a pure spirit of liberality, without the smallest previous claim on the score of merit. And shall not God, whose perfections are infinite, do more than this?”

Summations, Chapter 48
Context: Mercy is a sweet gracious working in love, mingled with plenteous pity: for mercy worketh in keeping us, and mercy worketh turning to us all things to good. Mercy, by love, suffereth us to fail in measure and in as much as we fail, in so much we fall; and in as much as we fall, in so much we die: for it needs must be that we die in so much as we fail of the sight and feeling of God that is our life. Our failing is dreadful, our falling is shameful, and our dying is sorrowful: but in all this the sweet eye of pity and love is lifted never off us, nor the working of mercy ceaseth.
For I beheld the property of mercy, and I beheld the property of grace: which have two manners of working in one love. Mercy is a pitiful property which belongeth to the Motherhood in tender love; and grace is a worshipful property which belongeth to the royal Lordship in the same love. Mercy worketh: keeping, suffering, quickening, and healing; and all is tenderness of love. And grace worketh: raising, rewarding, endlessly overpassing that which our longing and our travail deserveth, spreading abroad and shewing the high plenteous largess of God’s royal Lordship in His marvellous courtesy; and this is of the abundance of love. For grace worketh our dreadful failing into plenteous, endless solace; and grace worketh our shameful falling into high, worshipful rising; and grace worketh our sorrowful dying into holy, blissful life.
For I saw full surely that ever as our contrariness worketh to us here in earth pain, shame, and sorrow, right so, on the contrary wise, grace worketh to us in heaven solace, worship, and bliss; and overpassing. And so far forth, that when we come up and receive the sweet reward which grace hath wrought for us, then we shall thank and bless our Lord, endlessly rejoicing that ever we suffered woe. And that shall be for a property of blessed love that we shall know in God which we could never have known without woe going before.
And when I saw all this, it behoved me needs to grant that the mercy of God and the forgiveness is to slacken and waste our wrath.

2015, Eulogy for the Honorable Reverend Clementa Pinckney (June 2015)
Context: This whole week, I’ve been reflecting on this idea of grace. The grace of the families who lost loved ones. The grace that Reverend Pinckney would preach about in his sermons. The grace described in one of my favorite hymnals -- the one we all know: Amazing grace, how sweet the sound that saved a wretch like me. I once was lost, but now I’m found; was blind but now I see. According to the Christian tradition, grace is not earned. Grace is not merited. It’s not something we deserve. Rather, grace is the free and benevolent favor of God as manifested in the salvation of sinners and the bestowal of blessings.

Meditations on the Sacraments (1977), Introduction, p. xi.
Context: Grace is everywhere as an active orientation of all created reality toward God, though God does not owe it to any creature to give it this special orientation. Grace does not happen in isolated instances here and there in an otherwise profane and graceless world. It is legitimate, of course, to speak of grace-events which occur at discrete points in space and time. But then what we are really talking about is the existential and historical acceptance of this grace by human freedom. … Grace itself … is everywhere and always, even though a human being's freedom can sinfully say no to it, just as a human being's freedoms can protest against humankind itself. This immanence of grace in the conscious world always and everywhere does not take away the gratuity of grace, because God's immediacy out of self-giving love is not something anyone can claim as his or her due. The immanence of grace always and everywhere does not make salvation history cease to be history, because history is the acceptance of grace by the historical freedom of human beings and the history of spirit coming ever more to itself in grace.
