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.
The house of the devil is the world which lieth in wickedness, (1 John 5:19.) which he builds upon the earth, because those who obey him he drags down from heaven to earth; he builds without foundation, for sin has no foundation, standing not by its own nature, for evil is without substance, which yet whatever it is, grows up in the nature of good. But because the foundation is called so from fundus, we may not unfitly understand that fundamentum is placed here for fundus. As then he who is fallen into a well is kept at the bottom of the well, so the soul falling away remains stationary, as it were, at the very bottom, as long as it continues in any measure of sin. But not content with the sin into which it is fallen, while daily sinking into worse, it can find no bottom, as it were, in the well to which it may fix itself. But every kind of temptation increasing, both the really bad and the feignedly good become worse, until at last they come to everlasting punishment. Hence it follows, Against which the stream did beat vehemently. By the force of the stream may be understood the trial of the last judgment, when both houses being finished, the wicked shall go into everlasting punishment, but the righteous into life eternal. (Mat. 25:46.)
