Bede the Venerable
Catena Aurea · Lukasevangelium 6
And why call ye me, Lord, Lord, and do not the things which I say? Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock. But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth: against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.
Lest any one should vainly flatter himself with the words, Out of the abundance of the heart the mouth speaketh, as if words only and not rather works were required of a Christian, our Lord adds the following, But why call ye me Lord, Lord, and do not the things which I say? As if He said, Why do ye boast of sending forth the leaves of a right confession, and shew forth no fruit of good works.
