Life of Joseph F. Smith, pg. 45-46; “On the 3rd of June, the Elders from various parts of the country where they were laboring, came in; and the conference before appointed, convened in Kirtland, and the Lord displayed His power to the most perfect satisfaction of the Saints. The man of sin was revealed, and the authority of the Melchizedek Priesthood (i.e. office of High Priest) was manifested and conferred for the first time upon several Elders.” – Joseph Fielding Smith
2 Thessalonians 2:3-4; “Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.”
It makes you wonder who the man of sin was in that meeting and why is this group of grown men doing things like this?
