Bede the Venerable — as excerpted in the Catena Aurea on Luke 20:27-40

“Or He says this, that after having proved that the souls abide alter death, (which the Sadducees denied,) He might next introduce the resurrection also of the bodies, which together with the souls have done good or evil. But that is a true life which the just live unto God, even though they are dead in the body. Now to prove the truth of the resurrection, He might have brought much more obvious examples from the Prophets, but the Sadducees received only the five books of Moses, rejecting the oracles of the Prophets.”
