Psalms 23:2

2. “The earth is the Lord’s, and the fulness thereof, the compass of the world, and all they that dwell therein” ( ver. 1 ); when the Lord, being glorified, is announced for the believing of all nations; and the whole compass of the world becomes His Church. “He hath founded it above the seas.” He hath most firmly established it above all the waves of this world, that they should be subdued by it, and should not hurt it. “And hath prepared it above the rivers” ( ver. 2 ). The rivers flow into the sea, and men of lust lapse into the world: these also the Church, which, when worldly lusts have been conquered by the grace of God, hath been prepared by love for the reception of immortality, subdues.

7. But I have yet somewhat more to say on this head. For not only, indeed, does the magnitude and beauty of the creation, but also the very manner of it, display a God who is the artificer of the universe. For since we were not present at the beginning, whilst he was engaged in the work of forming and creating all things; nor had we been present, could we have known how they came into being, the power that disposed them being invisible; He hath made the mode of this creation to become our best teacher, by compounding all things in a manner which transcends the course of nature. Perhaps what I have said, is not sufficiently clear. Therefore it is necessary that I should again repeat it in a clearer manner. All men, then, must admit that it is the course of nature for water to be supported on the earth, and not the earth on the waters. …

8. And who is there that must not feel astonished and amazed at these things; and confidently pronounce that they are not the works of nature, but of that Providence which is above nature? Therefore one speaks thus: “Who hangeth the earth upon nothing.” And another observes, “In His hands are the corners of the earth.” And again: “He hath laid the foundation of it upon the seas.” And these declarations, though they seem contrary to one another, have yet an entire agreement. For he that said, “He hath laid the foundation of it upon the seas,” meant the same thing as he did who declared, “He hath hung it upon nothing.” For its standing upon the waters is just the same thing as hanging upon nothing. …

That is, that ye may get clear of that heartlessness ( ἀθυμίας ) towards one another, and may never be cast down by temptations. And this will be by your abounding in hope. Now this is the cause of all good things, and it comes from the Holy Ghost. But it is not simply from the Spirit, but on condition of our contributing our part also. This is why he says, “in believing.” For this is the way for you to be filled with joy, if ye believe, if ye hope. Yet he does not say if ye hope, but, “if ye abound in hope,” so as not to find comfort in troubles only, but even to have joy through the abundance of faith and hope. And in this way, ye will also draw the Spirit to you. In this way, when He is come ye will continually keep to all good things. …

9. Do you suppose that a heavier body prevents the earth from falling into the abyss? Then you must consider that this support needs itself a support to prevent it from falling. Can we imagine one? Our reason again demands yet another support, and thus we shall fall into the infinite, always imagining a base for the base which we have already found. And the further we advance in this reasoning the greater force we are obliged to give to this base, so that it may be able to support all the mass weighing upon it. Put then a limit to your thought, so that your curiosity in investigating the incomprehensible may not incur the reproaches of Job, and you be not asked by him, “Whereupon are the foundations thereof fastened?” If ever you hear in the Psalms, “I bear up the pillars of it;” see in these pillars the power which sustains it. …

The earth is one of the four elements, dry, cold, heavy, motionless, brought into being by God, out of nothing on the first day. For in the beginning , he said, God created the heaven and the earth : but the seat and foundation of the earth no man has been able to declare. Some, indeed, hold that its seat is the waters: thus the divine David says, To Him Who established the earth on the waters . Others place it in the air. Again some other says, He Who hangeth the earth on nothing . And, again, David, the singer of God, says, as though the representative of God, I bear up the pillars of it , meaning by “pillars” the force that sustains it. Further, the expression, He hath founded it upon the seas , shews clearly that the earth is on all hands surrounded with water. …
