We are all familiar with the hymn “O my Father,” which is often sung at LDS funerals. Written in 1845, this hymn by Eliza R. Snow, alludes to a Heavenly Mother. Sister Snow penned the lyrics to this hymn after Joseph Smith taught her about our heavenly parentage. When did the first presidency first publicly teach of a Heavenly Mother?
a. Heber C. Kimball
The first Mission President was Heber C. Kimball, who began serving in the British mission in 1837.
