Joseph Smith Quotes
The Church is not fully organized, in its proper order, and cannot be, until the Temple is completed, where places will be provided for the administration of the ordinances of the Priesthood.
What was the object of gathering the . . . people of God in any age of the world? . . . The main object was to build unto the Lord a house whereby He could reveal unto His people the ordinances of His house and the glories of His kingdom, and teach the people the way of salvation; for there are certain ordinances and principles that, when they are taught and practiced, must be done in a place or house built for that purpose.
The question is frequently asked "Can we not be saved without going through with all those ordinances, etc.?" I would answer, No, not the fullness of salvation. Jesus said, "There are many mansions in my Father's house, and I will go and prepare a place for you." [see John 14:1–2]
House here named should have been translated kingdom; and any person who is exalted to the highest mansion has to abide a celestial law, and the whole law too.
