“ One thing was to spread forth the light of truth, to preach the Gospel, to unfold the principles of eternal truth; and then when people had received the first principles of the Gospel, to teach them and more fully instruct them in the principles of eternal life. And hence the necessity of the priesthood. And what is that? The rule and government of God through the medium of which men whom he selects and chooses, which he has done in the different ages of time, are duly authorized and qualified to proclaim his will and administer his ordinances. ”
