Christ's Sermon on the Mount. In Manner and Contents It So Resembles the Creator's Dispensational Words and Deeds. It Suggests Therefore the Conclusion that Jesus is the Creator's Christ. The Beatitudes
I now come to those ordinary precepts of His, by means of which He adapts the peculiarity of His doctrine to what I may call His official proclamation as the Christ. “Blessed are the needy” (for no less than this is required for interpreting the word in the Greek, “because theirs is the kingdom of heaven.” Now this very fact, that He begins with beatitudes, is characteristic of the Creator, who used no other voice than that of blessing either in the first fiat or the final dedication of the universe: for “my heart,” says He, “has indited a very good word.” This will be that “very good word” of blessing which is admitted to be the initiating principle of the New Testament, after the example of the Old.
What is there, then, to wonder at, if He entered on His ministry with the very attributes of the Creator, who ever in language of the same sort loved, consoled, protected, and avenged the beggar, and the poor, and the humble, and the widow, and the orphan? So that you may believe this private bounty as it were of Christ to be a rivulet streaming from the springs of salvation. Indeed, I hardly know which way to turn amidst so vast a wealth of good words like these; as if I were in a forest, or a meadow, or an orchard of apples. I must therefore look out for such matter as chance may present to me.
