The Lord said: Verily I say unto you, Inasmuch as ye have done it unto one of the least of these My brethren, ye have done it unto Me (Matthew 25:40).
Similar things happen in almsgiving and in Holy Communion. In Holy Communion we receive the Living Lord Christ Himself, in the form of bread and wine; in almsgiving we give to the Living Lord Christ Himself, in the form of the poor and needy. A certain man in Constantinople was unusually merciful. Walking along the streets of the city, he would press his gift into the hands of the poor and hurry onward, so he would not hear their gratitude or be recognized. When a friend of his asked how he had become so merciful, he replied: “Once in church I heard a priest say that whoever gives to the poor, gives into the hands of Christ Himself. I didn’t believe it, for I thought, ‘How can this be, when Christ is in heaven?’ However, I was on my way home one day and I saw a poor man begging, and the face of Christ shone above his head! Just then a passerby gave the beggar a piece of bread, and I saw the Lord extend His hand, take the bread, and bless the donor. From then on, I have always seen Christ’s face shining above the beggars. Therefore, with great fear I perform as much charity as I can.’
