Love for our neighbor is preceded and accompanied by humility in our human relationships. Hatred toward our neighbor is preceded by condemnation and criticism of him, detraction and disparagement, slander and backbiting, scorn for him; in other words, by pride.
…[constantly] remember Christ’s words: “Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me.” [do not] stop to consider whether [your] neighbor deserves [your] respect or not; [pay] no attention to his numerous and obvious defects.
[Let your attention be] taken up with seeing that you do not somehow fail to realize that your neighbor is the image of God, and that Christ accepts what we do to our neighbor as if it were done to Him.
