History of the Church 5:1-2; “Inauguration of Endowment Ceremonies… And the communications I made to this council were of things spiritual, and to be received only by the I spiritual minded: and there was nothing made known to these men but what will be made known to all the Saints of the last days, so soon as they are prepared to receive, and a proper place is prepared to communicate them, even to the weakest of the Saints; therefore let the Saints be diligent in building the Temple, and all houses which they have been, or shall hereafter be, commanded of God to build; and wait their time with patience in all meekness, faith, perseverance unto the end, knowing assuredly that all these things referred to in this council are always governed by the principle of revelation.” – Wednesday, May 4, 1842
Matthew 5:33-34; “Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths: 34 But I say unto you, Swear not at all; neither by heaven; for it is God’s throne.”
This took place on Wednesday, May 4, 1842.
Could it be a coincidence the revelation for signs, tokens and handshakes were instituted into the temple endowment ceremony a mere six weeks after Smith became a Mason? I think not!
