Tractates on the Gospel of John

¹ In a certain place in the Gospel, the Lord says that the prudent hearer of His word ought to be like a man who, wishing to build a house, digs deeply until he comes to the foundation of stability on the rock, and there establishes in security what he builds against the violence of the flood; so that, when the flood comes, it may be rather beaten back by the strength of the building. than bring ruin on that house by the force of its pressure. Let us regard the Scripture of God to be, as it were, the field where we wish to build something. Let us not be slothful, nor be content with the surface; let us dig deeply until we come to the rock: “And that rock was Christ.”
