Ordinances instituted in the heavens before the foundation of the World in the Priesthood for the Salvation of men, are not to be altered or changed, all must be saved on the same principles.
If a man gets a fulness of the Priesthood of God he has to get it in the same way that Jesus Christ obtained it, and that was by keeping all the commandments and obeying all the ordinances of the house of the Lord.
