Joseph F. Smith on the "oneness" and Unity among the members of the Godhead

There is a oneness in the Godhead as well as a distinctness of personality. This oneness is emphasized in the sayings and writings of prophets and apostles in order to guard against the erroneous idea that these three may be distinct and independent deities and rivals for our worship. (Joseph F. Smith, “Answers to Gospel Questions,” Improvement Era, January 1901, 228)
