Thou hast set men over our heads. We have passed through tire and water, and thou hast brought us out into a refreshment.

“And although the entrance is "straight and narrow," once inside we see a vast and limitless space, greater than any other anywhere. We have been told of these things by eyewitnesses and heirs. They speak of their trials and distresses: "You have placed afflictions before us," but then they add, "You brought us out into a spacious place"—and, "You gave us space in our distress."”

“"And lead us not into temptation, O Lord." Is it this then what the Lord teaches us to pray, that we may not to be tempted at all? How, then, is it said elsewhere, "an untempted person is a person unproved"; and again, "My brothers, count it all joy when you fall into various temptations"? But does perchance the entering into temptation mean being overwhelmed by the temptation? For temptation is like a winter torrent difficult to cross. Those, therefore, who are not overwhelmed in temptations, pass through, showing themselves excellent swimmers and not being swept away by them at all; while those who are not such, enter into them and are overwhelmed. As for example, Judas having entered into the temptation of the love of money, did not swim through it but was overwhelmed and was strangled both in body and spirit. Peter entered into the temptation of the denial; but having entered, he was not overwhelmed by it but courageously swam through it and was delivered from the temptation. Listen again, in another place, to a company of unscathed saints, giving thanks for deliverance from temptation: "You, O God, have proved us; you have tried us by fire like silver is tried. You brought us into the net; you laid afflictions on our loins. You have caused people to ride over our heads; we went through fire and water; and you brought us out into a place of rest." You see them speaking boldly in regard to their having passed through and not been pierced. "But you brought us out into a place of rest"; now their coming into a place of rest is their being delivered from temptation.”

“"Thou hast laid tribulations on our back:" "Thou hast set men over our heads" (ver. 11). All these things the Church hath suffered in sundry and divers persecutions: She hath suffered this in Her individual members, even now doth suffer it. For there is not one, that in this life could say that he was exempt from these trials. Therefore there are set even men over our heads: we endure those whom we would not, we suffer for our betters those whom we know to be worse. But if sins be wanting, a man is justly superior: but by how much there are more sins, by so much he is inferior. And it is a good thing to consider ourselves to be sinners, and thus endure men set over our heads: in order that we also to God may confess that deservedly we suffer. For why dost thou suffer with indignation that which He doeth who is just? "Thou hast laid tribulations upon our back: Thou hast set men over our heads." God seemeth to be wroth, when He doeth these things: fear not, for a Father He is, He is never so wroth as to destroy. When ill thou livest, if He spareth, He is more angry. In a word, these tribulations are the rods of Him correcting, lest there be a sentence from Him punishing. ...”

“And again listen unto him, for he teacheth thee in another place that before a man hath gone through tribulations and hath been tried in the furnace of enduring labours patiently, he cannot go forth into the wide place of spiritual happiness, saying, "Thou hast brought me through fire and water, and hast brought me out into a wide place;" now he likeneth unto fire and water the afflictions, and wickedness, and labours which surround him on all sides, whether the afflictions arose from his own will, or from the chastisement of God which took place to try him, or from the wicked men who envied him his good works.”

“Fire and water, which the Egyptians considered as the emblems of purity, (Horus. xli.) and which here denote the greatest tribulations. (Calmet) — The just still overcome by God’s grace, (Worthington) notwithstanding all the efforts of tyrants who may be set over them. (Menochius)”
