c. 403–404 · John Chrysostom, Homilies on the Epistle to the Hebrews 11.3
Afterwards giving them full assurance, he says, “nay rather by hope.” And he said not, “We are within,” but ‘It hath entered within,’ which was more true and more persuasive. For as the anchor, dropped from the vessel, does not allow it to be carried about, even if ten thousand winds agitate it, but being depended upon makes it steady, so also does hope. And see how very suitable an image he has discovered: For he said not, Foundation; which was not suitable; but, “Anchor.” For that which is on the tossing sea, and seems not to be very firmly fixed, stands on the water as upon land, and is shaken and yet is not shaken. For in regard to those who are very firm, and philosophic, Christ with good reason made that statement, saying, “Whosoever hath built his house on a rock.” ( Matt. vii. 24 .) But in respect of those who are giving way, and who ought to be carried through by hope, Paul hath suitably set down this. For the surge and the great storm toss the boat; but hope suffers it not to be carried hither and thither, although winds innumerable agitate it: so that, unless we had this [hope] we should long ago have been sunk.
