At SS Union Board. Mtg. "The question was asked if partaking of the Sacrament would cause a forgiveness of sins. A question card used in Sunday Schools said it would. Father (Geo. Q. Cannon) said that partaking worthily of the Sacrament would gain for the Saint a forgiveness of sins, as well as a repentant spirit and humble prayer would bring the same blessing, yet this is not the ordinance instituted for the forgiveness of sins, and any question or answer which conveyed such an idea is incorrect."
