Theophylact of Ohrid
Catena Aurea · Markusevangelium 12
Then come unto him the Sadducees, which say there is no resurrection; and they asked him, saying, Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother. Now there were seven brethren: and the first took a wife, and dying left no seed. And the second took her, and died, neither left he any seed: and the third likewise. And the seven had her, and left no seed: last of all the woman died also. In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife. And Jesus answering, said unto them, Do ye not therefore err, because ye know not the Scriptures, neither the power of God? For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven. And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? He is not the God of the dead, but the God of the living: ye therefore do greatly err.
As if He had said, Ye understand not what sort of a resurrection the Scriptures announce; for ye believe that there will be a restoration of our bodies, such as they are now, but it shall not be so. Thus then ye know not the Scriptures; neither again do ye know the power of God; for ye consider it as a difficult thing, saying, How can the limbs, which have been scattered, be united together and joined to the soul? But this in respect of the Divine power is as nothing. There follows: For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven; as if He had said, There will be a certain heavenly and angelic restoration to life, when there shall be no more decay, and we shall remain unchanged; and for this reason marriage shall cease. For marriage now exists onaccount of our decay, that we may be carried on by succession of our race, and not fail; but then we shall be as the Angels, who need no succession by marriage, and never come to an end.
