For nothing can so make a man an imitator of Christ as caring for his neighbors. Indeed, even though you fast, or sleep on hard ground, or even suffer unto death, but should take no thought for your neighbor, you have done nothing great; despite what you have done, you will still stand far from this model of a perfect Christian.
The key to Divine gifts is given to the heart by love of neighbor, and, in proportion to the heart's freedom from the bonds of the flesh, the door of knowledge begins to open before it.
The guarding of the conscience with regard to one’s neighbor is doing absolutely nothing at all that we know will upset or wound him, either by deed, word, gesture or even a glance. Even a gesture, can wound one’s neighbor. Briefly, man infects his conscience by deliberately doing those things that he knows will provoke his neighbor and will harm and embarrass him. Therefore, to keep one’s conscience and not act in this manner, is what we mean by keeping our conscience towards our neighbor.
Each one, in undertaking any task, should have this purpose in mind: to serve the need of others, not his own ends. In this way he will escape the charge of self-love, and will receive a blessing for his fraternal love from the Lord Who said: As long as you did it to one of these my least brethren, you did it to me (Mt. 25:40).
We cannot be saved by seeking just our own individual salvation; we need to look first to the good of others. In warfare, the soldier who takes to flight to save his own skin brings disaster on himself as well as on the others, whereas the good soldier who takes up arms on behalf of his comrades saves his own life along with theirs.
Should you see your neighbor commit a sin, see that you think not only of his sin, but that you also think of what he does, and has done well, and doing this you will oftentimes find that he is better than you are; when you consider all he has done, and not a part. God does not judge a man on a part of his life only. He says: I knew their works and their thoughts; I come that I may gather them together. (Is. lxvi. 18).
When anyone is disturbed or saddened under the pretext of a good and soul-profiting matter, and is angered against his neighbor, it is evident that this is not according to God: for everything that is of God is peaceful and useful and leads a man to humility and to judging himself.
Whatever gentleness you use in speaking with others, that very same gentleness will Christ use with you. With whatever measure you measure out to others, with that very same measure will He apportion out to you. Just as you forgive the failings of others, He forgives yours. With whatever love and gentleness you seek Him, likewise will He appear to you.
Unceasing prayer means to have the mind always turned to God with great love, holding alive our hope in Him, having confidence in Him whatever we are doing and whatever happens to us. That is the attitude that the Apostle had when he wrote: ‘Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril? Neither death nor life nor any other creature shall be able to separate us from the love of God in Christ Jesus.’ [cf. Rom. 8:35-38]
We should look upon every believer alike, and suppose that Christ abides in each; we must have such loving disposition towards him as to be ready to lay down our life for him. We should never think or say that someone is evil, but, as is said, should see everyone as good. If you see someone attacked by the passions, hate not the brother but the passions attacking him.
Do you not mock at the faults of your neighbor; do you not despise him; do you not nourish hatred against him on account of them? 'Charity beareth all things.' Remember this, and bear with the faults and iniquities of your brother, that God may bear with yours. Have patience with the infirm members, for we are all one body in the Lord.
Therefore with your whole soul you should acknowledge yourself as worthy of enduring more than you already endure; remember the words which Christ the Savior spoke concerning a good deed done to one’s neighbor, words which should apply equally to every offensive word or deed against one’s neighbor. Whatever you have done to your neighbor, He says, you have done to Me.
