According to one critic of the Church, Mario Stephen Depillis, Joseph Smith
never made the Millerite mistake of predicting the exact date of the Second Coming and numbly avoided this trip for the rest of his career. (Mario Stephen Depillis, “The Development of Mormon Communitarianism” [PhD Dissertation; Yale University, 1960], 86)
Compare and contrast this with the repeated claim that Joseph taught that the Second Coming would take place in 1890/91 (e.g., Did Joseph Smith Predict that the Second Coming would happen in 1890/91? (cf. Vern Grosvenor Swanson on the Eschatological Timetable of Joseph Smith's April 6, 1843 Discourse; Joseph Smith III (1832-1914) Not Believing Jesus Would Come in 1890/91; Joseph Smith's March 10, 1844 Discourse Concerning William Miller and the Parousia)
