Gregory the Great, on Ezek 1:12

“And every one of them went straight forward: whither the impulse of the spirit was to go, thither they went: and they turned not when they went.”

“For there are many sins which we commit, but they do not seem serious to us because, loving ourselves with a private love and closing our eyes, we flatter ourselves in our self-deception. Hence it often happens that we judge our own serious faults lightly, while judging the light faults of our neighbors severely. For it is written: "Men shall be lovers of themselves." And we know that private love powerfully closes the eye of the heart. From this it happens that what we ourselves do, and do not consider to be serious, is often done by our neighbor, and seems to us excessively detestable. But why does what seemed trivial to us in ourselves appear serious in our neighbor, unless because we neither see ourselves as we see our neighbor, nor our neighbor as we see ourselves? For if we looked at ourselves as we do at our neighbor, we would see our own faults with strict judgment. And again, if we looked at our neighbor as we do at ourselves, his action would never appear intolerable to us, since we have often perhaps done the same things, and thought we had done nothing intolerable to our neighbor. Moses strove to correct this badly divided judgment of our mind through the precept of the law, when he said that the bushel should be just and the measure equal. Hence Solomon says: "A weight and a weight, a measure and a measure, both are abominable before God." We know that in the double weights of merchants, one is larger, the other smaller. For they have one weight by which they weigh for themselves, and another weight by which they weigh for their neighbor. They prepare lighter weights for giving, but heavier ones for receiving. Therefore every person who weighs differently the things that belong to their neighbor and differently those that are their own has "a weight and a weight." Both therefore are abominable before God, because if one loved their neighbor as themselves, they would love them in good things as they love themselves. And if one looked at themselves as they do at their neighbor, they would judge themselves in evil things as they judge their neighbor. We ought therefore to see ourselves carefully as we see others, and, as has been said, to place ourselves before our own eyes, so that constantly imitating the winged creatures, lest we be ignorant of what we do, we may always walk before our own face. But the perverse, as we said a little before, do not walk before their own face, because they never consider what they do; they tend toward destruction; they exult in wicked deeds. Of whom it is written: "Who rejoice when they have done evil, and exult in the worst things." Often indeed the just person who beholds them weeps, but they themselves, in the manner of the frenzied, are lamented over, yet they laugh.”
