"The Holy Ghost is [the Father and the Son’s] minister to bring truths to our remembrance, to reveal new truths to us, and teach, guide, and direct the course of every mind, until we become perfected and prepared to go home, where we can see and converse with our Father in Heaven."

- Brigham Young, Teachings of Presidents of the Church: Brigham Young, (1997), 28–35, Chapter 4: Knowing and Honoring the Godhead
