An excerpt from a Commentary on Psalm 101
Yet even though he treated them so lovingly and generously, the Israelites were ungrateful and seemed forgetful to all of this. They abandoned the worship of God and more than once they were guilty of the abominable sin of idolatry.
Then he also took pity on us, when we were pagans who went off to mute idols wherever we were led. He severed us from the wild olive tree of paganism and, breaking our natural branches, he grafted us onto the true olive tree of Judaism and made us share in the root of his grace and its richness. Finally, he did not spare his own Son but gave him up for us all, an offering and a sacrifice to God in a fragrant odor, that he might redeem us from all our iniquity and cleanse for himself an acceptable people.
Now all these things are not merely certain arguments but also clear proof of his deep love and kindness for us. And yet we are the most ungrateful of men. Indeed, we have gone beyond the bounds of ingratitude: we give no thought to his love, nor do we recognize the extent of his kindnesses to us. Rather we reject the one who lavishes so many favors and even appear to despise him; and the remarkable mercy that he has continually shown to sinners does not move us to form our lives and conduct according to his most holy command.
Clearly these things are worthy to be written down in the second generation so as to preserve their memory for ever. Thus all who are still to be counted among Christians will know the great kindness of God toward us and never cease singing his divine praises.
and to the Son
and to the Holy Spirit:
as it was in the beginning,
is now, and will be forever. Amen
