6 But if you will, even from that wicked demon prove thou this. For what can be baser than the devil, because he had exalted himself; what higher than the man who is willing to abase himself? For the former crawls on the ground under our heel (For, “ye tread,” He says, “upon serpents and scorpions”), but the latter is set with the angels on high.
But if you desire to learn this from the example of haughty men also, consider that barbarian king, that led so great an army, who knew not so much as the things that are manifest to all; as, for instance, that stone was stone, and the images, images; wherefore he was inferior even to these. But the godly and faithful are raised even above the sun; than whom what can be higher, who rise above even the vaults of heaven, and passing beyond angels, stand by the very throne of the king.
And that you may learn in another way their vileness; who will be abased? He who has God for his ally, or he with whom God is at war? It is quite plain that it is he with whom He is at war. Hear then touching either of these what says the Scripture. “God resists the proud, but gives grace unto the humble.”
Again, I will ask you another thing also. Which is higher? He who acts as a priest to God and offers sacrifice? Or he who is somewhere far removed from confidence towards Him? And what manner of sacrifice does the lowly man offer? One may say. Hear David saying, “The sacrifice of God is a contrite spirit; a contrite and humbled heart God will not despise.”
Do you see the purity of this man? Behold also the uncleanness of the other; for “every one that is proud in heart is unclean before God.” Besides, the one has God resting upon him, (“For unto whom will I look,” says He, “but to him that is meek and quiet, and trembles at my words”), but the other crawls with the devil, for he that is lifted up with pride shall suffer the devil's punishment. Wherefore Paul also said, “Lest, being lifted up with pride, he should fall into the condemnation of the devil.”
And the thing opposite to what he wishes, befalls him. For his wish is to be arrogant, that he may be honored; but the most contemned of all is this character. For these most of all are laughing stocks, foes and enemies to all men, the most easy to be subdued by their enemies, the men that easily fall into anger, the unclean before God.
What then can be worse than this, for this is the extremity of evils? And what is sweeter than the lowly, what more blessed, since they are longed after, and beloved of God? And the glory too that comes of men, these do most of all enjoy, and all honor them as fathers, embrace them as brothers, receive them as their own members.
Let us then become lowly, that we may be high. For most utterly does arrogance abase. This abased Pharaoh. For, “I know not,” he says, “the Lord,” and he became inferior to flies and frogs, and the locusts, and after that with his very arms and horses was he drowned in the sea. In direct opposition to him, Abraham says, “I am dust and ashes,” and prevailed over countless barbarians, and having fallen into the midst of Egyptians, returned, bearing a trophy more glorious than the former, and, cleaving to this virtue, grew ever more high. Therefore he is celebrated everywhere, therefore he is crowned and proclaimed; but Pharaoh is both earth and ashes, and if there is anything else more vile than these. For nothing does God so abhor as arrogance. For this object has He done all things from the beginning, in order that He might root out this passion. Because of this are we become mortal, and are in sorrows, and wailings. Because of this are we in toil, and sweat, and in labor continual, and mingled with affliction. For indeed out of arrogance did the first man sin, looking for an equality with God. Therefore, not even what things he had, did he continue to possess, but lost even these.
For arrogance is like this, so far from adding to us any improvement of our life, it subtracts even what we have; as, on the contrary, humility, so far from subtracting from what we have, adds to us also what we have not.
This virtue then let us emulate, this let us pursue, that we may both enjoy present honor, and attain unto the glory to come, by the grace and love towards man of our Lord Jesus Christ, with whom be unto the Father glory and might, together with the Holy Ghost, now and always, and world without end. Amen.
