“The Journal of Discourses deservedly ranks as one of the standard works of the Church.”

George Q. Cannon – 1861, Journal of Discourses – Volume 8 (London, England: George Q. Cannon, 1861), iii, “Preface.”

Even the church acknowledges that the 26-volume digest contains significant errors. However, they are hesitant to specify which parts are incorrect, leaving students of Mormonism to question its overall reliability.
