5 They show, further, that that Horos of theirs, whom they call by a variety of names, has two faculties,— the one of supporting, and the other of separating; and in so far as he supports and sustains, he is Stauros, while in so far as he divides and separates, he is Horos. They then represent the Saviour as having indicated this twofold faculty: first, the sustaining power, when He said, “Whosoever does not bear his cross (Stauros), and follow after me, cannot be my disciple;” and again, “Taking up the cross, follow me;” but the separating power when He said, “I came not to send peace, but a sword.” They also maintain that John indicated the same thing when he said, “The fan is in His hand, and He will thoroughly purge the floor, and will gather the wheat into His garner; but the chaff He will burn with fire unquenchable.” By this declaration He set forth the faculty of Horos.
For that fan they explain to be the cross (Stauros), which consumes, no doubt, all material objects, as fire does chaff, but it purifies all those who are saved, as a fan does wheat. Moreover, they affirm that the Apostle Paul himself made mention of this cross in the following words: “The doctrine of the cross is foolishness to those who perish, but to us who are saved it is the power of God.” And again: “God forbid that I should glory in anything save in the cross of Christ, by whom the world is crucified to me, and I unto the world.”
