Master, Moses wrote, &c.— The Sadducees are thought by many to have agreed with the Samaritans in rejecting all the other parts of holyScripture but the five books of Moses. See the Inferences from Matthew 22. But there are others who strenuously maintain the contrary; and it is most reasonable to believe, that they did not absolutely reject the other books of the Old Testament, but only gave a great preference to the Pentateuch; and, laying it down as a principle to receive nothing as an article of faith, which could not be proved from the law, if any thing was urged from other parts of Scripture that could not be deduced from Moses, they would explain it in some other way: and this might be sufficient to induce our Lord to bring his argument to prove the resurrection from what Moses had said, and to confirm it by that part of Scripture which was most regarded by the Sadducees, and upon which they now had grounded their objection to it. See Serrarius, Lightfoot, and Doddridge.
