+Mk 12: 18-27
Some Sadducees, who say there is no resurrection, came to him and put this question to him,
saying, “Teacher, Moses wrote for us, ‘If someone’s brother dies, leaving a wife but no child, his brother must take the wife and raise up descendants for his brother.’
Now there were seven brothers. The first married a woman and died, leaving no descendants.
So the second married her and died, leaving no descendants, and the third likewise.
And the seven left no descendants. Last of all the woman also died.
At the resurrection (when they arise) whose wife will she be? For all seven had been married to her.”
Jesus said to them, “Are you not misled because you do not know the scriptures or the power of God?
When they rise from the dead, they neither marry nor are given in marriage, but they are like the angels in heaven.
As for the dead being raised, have you not read in the Book of Moses, in the passage about the bush, how God told him, ‘I am the God of Abraham, (the) God of Isaac, and (the) God of Jacob’?
He is not God of the dead but of the living. You are greatly misled.”

The progressive revelation of the Resurrection
992 God revealed the resurrection of the dead to his people progressively. Hope in the bodily resurrection of the dead established itself as a consequence intrinsic to faith in God as creator of the whole man, soul and body. The creator of heaven and earth is also the one who faithfully maintains his covenant with Abraham and his posterity. It was in this double perspective that faith in the resurrection came to be expressed. In their trials, the Maccabean martyrs confessed:
The King of the universe will raise us up to an everlasting renewal of life, because we have died for his laws. One cannot but choose to die at the hands of men and to cherish the hope that God gives of being raised again by him.
993 The Pharisees and many of the Lord’s contemporaries hoped for the resurrection. Jesus teaches it firmly. To the Sadducees who deny it he answers, “Is not this why you are wrong, that you know neither the scriptures nor the power of God?” Faith in the resurrection rests on faith in God who “is not God of the dead, but of the living.”
994 But there is more. Jesus links faith in the resurrection to his own person: “I am the Resurrection and the life.” It is Jesus himself who on the last day will raise up those who have believed in him, who have eaten his body and drunk his blood. Already now in this present life he gives a sign and pledge of this by restoring some of the dead to life, announcing thereby his own Resurrection, though it was to be of another order. He speaks of this unique event as the “sign of Jonah,” the sign of the temple: he announces that he will be put to death but rise thereafter on the third day.
995 To be a witness to Christ is to be a “witness to his Resurrection,” to “[have eaten and drunk] with him after he rose from the dead.” Encounters with the risen Christ characterize the Christian hope of resurrection. We shall rise like Christ, with him, and through him.
996 From the beginning, Christian faith in the resurrection has met with incomprehension and opposition. “On no point does the Christian faith encounter more opposition than on the resurrection of the body.” It is very commonly accepted that the life of the human person continues in a spiritual fashion after death. But how can we believe that this body, so clearly mortal, could rise to everlasting life?
