“God … revealed himself [to Joseph Smith] as a personal being. Furthermore, the Father and the Son demonstrated the undeniable truth that they are separate and distinct personages. Indeed, the relationship of the Father and the Son was reaffirmed by the divine introduction to the boy prophet, ‘This is My Beloved Son. Hear Him!’ [Joseph Smith —History 1:17]” (Teachings of Presidents of the Church: Howard W. Hunter, p. 89).
