Six months before his death the Prophet Joseph Smith declared: "I have tried for a number of years to get the minds of the Saints prepared to receive the things of God; but we frequently see some of them, after suffering all they have for the work of God, will fly to pieces like glass as soon as anything comes that is contrary to their traditions." (Smith, Teachings of the Prophet Joseph Smith, p. 331) Of what traditions is he speaking? Not infant damnation, or baptism by sprinkling, or Neoplatonic ideas about God, for such things the Saints had left behind. The traditionalism to which he refers is clear from another address given by the Prophet at about the same time, when he said, "I suppose I am not allowed to go into an investigation of anything that is not contained in the Bible. If I do, I think there are so many over-wise men here, that they would cry 'treason' and put me to death." (Smith, Teachings of the Prophet Joseph Smith, p. 348)
