Discourses of Brigham Young, pg. 257; “I hope to see the time when we shall have a reformation in the orthography of the English language, among this people, for it is greatly needed. Such a reformation would be a great benefit, and would make the acquirement of an education much easier than at present. 12:174.”
2 Peter 2:12; “But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption.”
The reason they needed to change the “orthography” of the English language is so they can change their ideology of who God is while keeping a tight control of the people. This speech by Brigham Young took place during the time of their experiment with the Deseret Alphabet.
