Isaias 63:16

16. Why should we not believe these to be angelic operations through dispensation of the providence of God, Who maketh good use of both good things and evil, according to the unsearchable depth of His judgments? whether thereby the minds of mortals be instructed, or whether deceived; whether consoled, or whether terrified: according as unto each one there is to be either a showing of mercy, or a taking of vengeance, by Him to Whom, not without a meaning, the Church doth sing “of mercy and of judgment.” Let each, as it shall please him, take what I say. If the souls of the dead took part in the affairs of the living, and if it were their very selves that, when we see them, speak to us in sleep; to say nothing of others, there is my own self, whom my pious mother would no night fail to visit, that mother who by land and sea followed me that she might live with me. …

17. Some man may say: “If there be not in the dead any care for the living, how is it that the rich man, who was tormented in hell, asked father Abraham to send Lazarus to his five brothers not as yet dead, and to take course with them, that they should not come themselves also into the same place of torments?” But does it follow, that because the rich man said this, he knew what his brethren were doing, or what they were suffering at that time? Just in that same way had he care for the living, albeit what they were doing he wist not at all, as we have care for the dead, albeit what they do we confessedly wot not. For if we cared not for the dead, we should not, as we do, supplicate God on their behalf. In fine, Abraham did not send Lazarus, and also answered, that they have here Moses and the Prophets, whom they ought to hear that they might not come to those torments. …

16. Further, what said the evangelist as he went on? “Therefore the Jews sought the more to kill Him, because He not only broke the Sabbath, but said also that God was His Father;” not in any ordinary manner, but how? “Making Himself equal with God.” For we all say to God, “Our Father which art in heaven;” we read also that the Jews said, “Seeing Thou art our Father.” Therefore it was not for this they were angry, because He said that God was His Father, but because He said it in quite another way than men do. Behold, the Jews understand what the Arians do not understand. The Arians, in fact, say that the Son is not equal with the Father, and hence it is that the heresy was driven from the Church. Lo, the very blind, the very slayers of Christ, still understood the words of Christ. …

10. Thus much then at present, in the way of a digression, to put you in remembrance. Let me, however, add yet another testimony in proof that God is called the Father of men in an improper sense. For when in Esaias God is addressed thus, For Thou art our Father, though Abraham be ignorant of us , and Sarah travailed not with us , need we inquire further on this point? And if the Psalmist says, Let them be troubled from His countenance, the Father of the fatherless, and Judge of the widows , is it not manifest to all, that when God is called the Father of orphans who have lately lost their own fathers, He is so named not as begetting them of Himself, but as caring for them and shielding them. …

3. To speak in a more feeling strain, trusting in Him Who then forsook me, as in a Father, “Abraham has been ignorant of us, Israel has acknowledged us not, but Thou art our Father, and unto Thee do we look; beside Thee we know none else, we make mention of Thy name.” Therefore, says Jeremiah, I will plead with Thee, I will reason the cause with Thee. We are become as at the beginning, when Thou barest not rule over us, and Thou hast forgotten Thy holy covenant, and shut up Thy mercies from us. …
