Catena Aurea · Lukasevangelium 4
And all bare him witness, and wondered at the gracious words which proceeded out of his mouth. And they said, Is not this Joseph’s son? And he said unto them, Ye will surely say unto me this proverb, Physician, heal thyself: whatsoever we have heard done in Capernaum, do also here in thy country. And he said, Verily I say unto you, No prophet is accepted in his own country. But I tell you of a truth, many widows were in Israel in the days of Elias, when the heaven was shut up three years and six months, when great famine was throughout all the land; But unto none of them was Elias sent, save unto Sarepta, a city of Sidon, unto a woman that was a widow. And many lepers were in Israel in the time of Eliseus the prophet; and none of them was cleansed, saving Naaman the Syrian.
But this is given for an example, that in vain can you expect the aid of Divine mercy, if you grudge to others the fruits of their virtue. The Lord despises the envious, and withdraws the miracles of His power from them that are jealous of His divine blessings in others. For our Lord’s Incarnation is an evidence of His divinity, and His invisible things are proved to us by those which are visible. See then what evils envy produces. For envy a country is deemed unworthy of the works of its citizen, which was worthy of the conception of the Son of God.
