[Joseph Smith Sermon] Joseph the Seer Called upon me & others of the Twelve to attend meeting at his house. We did so in the evening & herd many good principles presented by presidents Joseph & Hyrum Smith such as the following: Speak not in tongues to your own nation but to those of annother tongue. Then if one of another tongue interpets it will be a sign to the unbeliever, & then it would condemn those who heard if they rejected it for the Lord does not work in vain. Joseph spoke upon the 14 ch. 1 cor. Prophesies will cease &c ie. A person will cease or stop prophesying & not continue all the while &c untill we come to perfection or a fulness. Then part work will be done away. [Wilford Woodruff Diary]
