Isaías 50:1
Hear what the prophet says: "You have been sold for your sins, and for your iniquities I sent your mother away." You see, therefore, that we are all creatures of God. But each one is sold for his own sins and, for his own iniquities, separates from his Creator. We, therefore, belong to God insofar as we have been created by him. But we have become slaves of the devil insofar as we have been sold for our sins. Christ came, however, and "bought us back" when we were serving that lord to whom we sold ourselves by sinning. And so [Christ] appears to have recovered as his own those whom he created; to have acquired as people belonging to another, indeed, those who had sought another Lord for themselves by sinning. — HOMILIES ON EXODUS 6:9
Isaías 50:11
If then this is the character of the body that rises from the dead, let us now see what is the meaning of the threatened "eternal fire." Now we find in the prophet Isaiah that the fire by which each person is punished is described as belonging to himself. For it says, "Walk in the light of your fire and in the flame which you have kindled for yourselves." These words seem to indicate that every sinner kindles for himself the flame of his own fire and is not plunged into a fire that has been previously kindled by someone else or that existed before him. — ON FIRST PRINCIPLES 2:10.4
Isaías 50:11
This "fire" is not "from the altar." The fire that is "from the altar" is the fire of the Lord. But that which is outside the altar is not of the Lord but is properly of each one who sins.… This fire is of those who have ignited it, just as it also was written in other places, "Walk in your fire and in the flame which you kindled for yourselves." But to Isaiah his own fire was not applied but the fire of the altar that "will cleanse his lips." — HOMILIES ON LEVITICUS 9:8.1
