Origen
Catena Aurea · Matthäusevangelium 22
The same day came to him the Sadducees, which say that there is no resurrection, and asked him, Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother: Likewise the second also, and the third, unto the seventh. And last of all the woman died also. Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Jesus answered and said unto them, Ye do err, not knowing the Scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. And when the multitude heard this, they were astonished at his doctrine. PSEUDO-DIONYSIUS. (de Divin. Nom. i.) For then when we shall be incorruptible and immortal, by the visible presence of God Himself we shall be filled with most chaste contemplations, and shall share the gift of light to the understanding in our impassible and immaterial soul after the fashion of the exalted souls in heaven; on which account it is said that we shall be equal to the Angels.
God moreover is He who says, I am that I am; (Ex. 3:14.) so that it is impossible that He should be called the God of those who are not. And see that He said not, I am the God of Abraham, Isaac, and Jacob, but The God of Abraham, the God of Isaac, and the God of Jacob. But in another place He said thus, The God of the Hebrews hath sent me unto thee. (Exod. 7:16.) For they who in comparison of other men are most perfect before God, have God entirely in them, wherefore He is not said to be their God in common, but of each in particular. As when we say, That farm is theirs, we shew that each of them does not own the whole of it; but when we say, That farm is his, we mean that he is owner of the whole of it. When then it is said, The God of the Hebrews, this shews their imperfection, that each of them has some small portion in God. But it is said, The God of Abraham, the God of Isaac, and the God of Jacob, because each one of these possessed God entirely. And it is to the no small honour of the Patriarehs that they lived to God.
