Basil the Great
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.
(in Princ. Prov.) But lay your foundations upon a rock, that is, lean upon the faith of Christ, so as to persevere immoveable in adversity, whether it come from man or God.
