In his book, John Stott tried to highlight and consider those truths that Christ defended in disputes with the Pharisees and Sadducees. Jesus Christ taught that morality and worship pleasing to God must come from the heart and that our greatest desire in life should be to seek not our own glory, but the glory of God. All of this is clear from Jesus’ disagreements with the religious leaders of his time. Jesus explained the errors of the Sadducees by the fact that they did not know the power of God, and, polemicizing with the Pharisees, He argued that the source of authority for us should be only the Word of God without the addition of human traditions. None of these disputes have yet been resolved. And first of all, we should be interested in which side will we be on: the side of Christ or His opponents? What is our Christianity in reality: truly Christian or is it just a modern version of Pharisaism or Sadduceeism?
