Never since the foundation of this Church was laid, have we seen manifested a greater willingness to comply with the requisitions of Jehovah, a more ardent desire to do the will of God, more strenuous exertions used, or greater sacrifices made than there have been since the Lord said, "Let the Temple be built by the tithing of my people."
Teachings of the Prophet Joseph Smith, sel. Joseph Fielding Smith (1976), 230.
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.
History of the Church, 6:184.
This is the spirit of Elijah, that we redeem our dead, and connect ourselves with our fathers which are in heaven, and seal up our dead to come forth in the first resurrection; and here we want the power of Elijah to seal those who dwell on earth to those who dwell in heaven.
History of the Church, 6:252.
The doctrine or sealing power of Elijah is as follows: If you have power to seal on earth and in heaven, then we should be wise. The first thing you do, go and seal on earth your sons and daughters unto yourself, and yourself unto your fathers in eternal glory.
Teachings of the Prophet Joseph Smith, sel. Joseph Fielding Smith (1976), 340.
All those who have not had an opportunity of hearing the Gospel, and being administered unto by an inspired man in the flesh, must have it hereafter, before they can be finally judged. It is no more incredible that God should save the dead, than he should raise the dead.
History of the Church, 4:425–26.
The spirit, power, and calling of Elijah is, that ye have power to hold the key of the revelation, ordinances, oracles, powers and endowments of the fullness of the Melchizedek Priesthood and of the kingdom of God on the earth; and to receive, obtain, and perform all the ordinances belonging to the kingdom of God, even unto the turning of the hearts of the fathers unto the children, and the hearts of the children unto the fathers, even those who are in heaven.
History of the Church, 6:251; spelling modernized.
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.
History of the Church, 4:603.
Joseph Smith explained the need for a temple this way: "We must have all things prepared and call our solemn assembly as the Lord has commanded us, that we may be able to accomplish his great work: and it must be done in God's own way; the house of the Lord must be prepared, and the solemn assembly called and organized in it according to the order of the house of God."

[In] "the dispensation of the fullness of times, when God will gather together all things that are in heaven, and all things that are upon the earth, even in one," . . . the Saints of God will be gathered in one from every nation, and kindred, and people, and tongue, . . . and all things whether in heaven or on earth will be in one, even in Christ. The heavenly Priesthood will unite with the earthly, to bring about those great purposes; and whilst we are thus united in the one common cause, to roll forth the kingdom of God, the heavenly Priesthood are not idle spectators, the Spirit of God will be showered down from above, and it will dwell in our midst. The blessings of the Most High will rest upon our tabernacles.
History of the Church, 4:610; punctuation modernized.
Believing the time has now come, when it is necessary to erect a house of prayer, a house of order, a house for the worship of our God, where the ordinances can be attended to agreeably to His divine will. . . . it behooves the Saints to weigh the importance of these things, in their minds, [and] . . . resolve to do all they can, and feel themselves as much interested as though the whole labor depended on themselves alone. By so doing they will emulate the glorious deeds of the fathers, and secure the blessings of heaven upon themselves and their posterity to the latest generation. To those who feel thus interested, and can assist in this great work, we say, let them . . . assist in the rolling on of the Kingdom, . . . and rise higher and higher in the scale of intelligence until they can "comprehend with all Saints what is the breadth and length, and depth and height; and to know the love of Christ which passeth knowledge."
History of the Church, 4:186.
Joseph recalled that during the dedication, "George A. Smith arose and began to prophesy, when a noise was heard like the sound of a rushing mighty wind, which filled the Temple, and all the congregation simultaneously arose, being moved upon by an invisible power; many began to speak in tongues and prophesy; others saw glorious visions; and I beheld the Temple was filled with angels, which fact I declared to the congregation. The people of the neighborhood came running together (hearing an unusual sound within, and seeing a bright light like a pillar of fire resting upon the Temple), and were astonished at what was taking place."
History of the Church, 2:428.
The Temple of the Lord is in process of erection here [Nauvoo], where the Saints will come to worship the God of their fathers, according to the order of His house and the powers of the Holy Priesthood, . . . and where instructions from the Most High will be received, and from this place go forth to distant lands.
History of the Church, 4:269.
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.
