Two things there are which He says they know not, the Scriptures and the power of God, by which is brought to pass the resurrection, and the new life in it.
Or by the power of God, which the Lord here convicts the Sadducees that they knew not, He intends Himself, who was the power of God; and Him they knew not [marg. note: 1 Cor 1:24], as not knowing the Scriptures which spoke of Him; and thence also they believed not the resurrection, which He should effect. But it is asked when the Saviour says, “Ye do err not knowing the Scriptures,” if He means that this text, “They neither marry, nor are given in marriage,” is in some Scripture, though it is not read in the Old Testament? We say that these very words are indeed not found, but that the truth is in a mystery implied in the moral sense of Scripture; the Law, which is “a shadow of good things to come,” whenever it speaks of husbands and wives, speaks chiefly of spiritual wedlock.
But neither this do I find any where spoken in Scripture that the Saints shall be after their departure as the Angels of God, unless one will understand this also to be inferred morally; as where it is said, “And, thou shalt go to thy fathers,” [Gen 15:15] and “He was gathered to his people.” [Gen 25:8] Or one may say; He blamed them that they read not the other Scriptures which are besides the Law, and therefore they erred.
Another says, That they knew not the Scriptures of the Mosaic Law, for this reason, that they did not sift their divine sense.
