It’s disturbing (and rightly so) that the church is so embarrassed by Joseph Smith marrying a 14-year-old that they ‘couch’ the language to lessen the blow on their website, stating:
“Helen Mar Kimball, daughter of Joseph’s close friends Heber C. and Vilate Murray Kimball, who was sealed to Joseph several months before her 15th birthday. Marriage at such an age, inappropriate by today’s standards…”
Plural Marriage in Kirtland and Nauvoo (Salt Lake City, UT: The Church of Jesus Christ of Latter-day Saints, 2021 on-line edition), 1.
…but apparently not too young by God’s standards?
In the four examples shown in this meme, it was OK for prophets of God to marry 14-15 year old girls from at least 1843 (Kimball/Smith) to 1871 (Jensen/Snow); a span of 28 years.
