Matthew 22:29 - Ellicott's Commentary On The Whole Bible

Ye do err. — This is, it may be noted, the one occasion in the Gospel history in which our Lord comes into direct collision with the Sadducees. On the whole, while distinctly condemning and refuting their characteristic error, the tone in which He speaks is less stern than that in which He addresses the Pharisees. They were less characterised by hypocrisy, and that, as the pessima corruptio optimi, was that which called down His sternest reproof. The causes of their error were, He told them, two-fold: (1) an imperfect knowledge even of the Scriptures which they recognised; (2) imperfect conceptions of the divine attributes, and therefore an à priori limitation of the divine power. They could not conceive of any human fellowship in the life of the resurrection except such as reproduced the relations and conditions of this earthly life.
