v 32 “When they heard Paul speak about the resurrection of the dead, some laughed in contempt, but others said, ‘We want to hear more about this later.'”
To the Greeks, the idea of bodily resurrection was a ridiculous idea. Either all we have is this material world and nothing more or if there was anything after this life, it was the freedom from this material world into the world of spirit and ideas. What they found funny was why anyone would want this body again. There was a severe distaste of the human body and all its bodily functions.
The Christian resurrection that though this material world is not all there is, the material world is good. It does not fall into monism, only the material or only the ideal and the other is only illusion, or into a dualism, total separation. It is dialectic at its truest form, not in fancy arguments but in proof of a new life.
Resurrection says that the spirit and the body is always one and that a transformation happens where they become more one, and so so the spirit is glorified body, and the body is spirit more fully enfleshed. My spirit and my body is no longer at war, as Paul says, but that indeed they have been completely reconciled.
Resurrection sounds funny, but only to those who have given up on true hope and accepted cynicism and doubt, those who who settle for the simplistic ideas that keep our brains happily sedated, accepting only things that make sense.
But for those with faith, with the energy to continue to exercise our brains to grope towards what is complex but true, resurrection is the surest proof of what we have always believed, this current existence in body and spirit.
