Cyril of Alexandria : The meaning of this is as follows: They have approached and come together, no longer staying apart, not alienated from each other through sin but as if brought close through spiritually taking possession, are joined into one faith and a common spirit. For once they tasted of the Lord and understood that he is good and began to wonder at the beauty of his truth, they did not only keep the gift for themselves but each one generously came to the aid of his brother and his friend. — COMMENTARY ON Isaiah 3:5.41:4-6 Eusebius of Caesarea : You, Jacob, now ponder such things, the Savior of everything did not privilege you over the salvation of other human beings but chose the things that suited you, while to the rest of the nations he announced an exchange, summoning them all to knowledge of him.… He calls "islands" the churches from all the nations, since those partially submerged under the evil of life are like those islands in the sea.…For it is not only those who are called who come to salvation, but also those nearby according to the laws of neighbor love (philanthropy). So they say these things to those worshiping God nearby, who would like to be their brothers and friends yet who are still "out of place." There was a time when our own craftsman prevailed, beating out idols, and the smith struck with a hammer his gods. But now we know that they are nothing and recognize the illusion of our forefathers. — COMMENTARY ON Isaiah 2:19 Theodoret of Cyrus : Those who formerly have been in error, as soon as they have benefited from the light of the knowledge of God, cannot bear to hide his glory but call all people to participate in it. "And one will say," that is to say, one who is removed from the darkness of ignorance. — COMMENTARY ON Isaiah 12:41.6
