Our Lord's Sermon on the Mount

If any one will piously and soberly consider the sermon which our Lord Jesus Christ spoke on the mount, as we read it in the Gospel according to Matthew, I think that he will find in it, so far as regards the highest morals, a perfect standard of the Christian life: and this we do not rashly venture to promise, but gather it from the very words of the Lord Himself. For the sermon itself is brought to a close in such a way, that it is clear there are in it all the precepts which go to mould the life. For thus He speaks: “Therefore, whosoever heareth these words of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: and the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
