The “stone cut out of the mountain without hands” (Dan. 2:44-45) is not a corruptible institution but an incorruptible Gospel.
There is no organization currently ministering the “gift of the Holy Ghost” as a right conferred upon an individual to remain always with them. There is an admonishment directing people to: “receive the Holy Ghost.” That admonishment is directed to the individual as advice, counsel or an objective to seek for, not as a right conferred indelibly upon them. (See, David Bednar, Receive the Holy Ghost, April 2010 General Conference; That We May Always Have His Spirit To Be With Us, April 2006 General Conference.) As recently as the Sunday morning session of the last LDS conference, President Eyring explained the limits of the LDS connection to the Holy Ghost. “We desire it, yet we know from experience that it is not easy to maintain. We each think, say, and do things in our daily lives that can offend the Spirit.” (The Holy Ghost as Your Companion.) Anyone of any faith anywhere in the world can have the same experience as a transitory gift from God. (Moroni 10:4-5.) Remember God gives liberally to all; the wicked and the righteous. People of faith throughout the world have as much access to the Holy Ghost as a latter-day saint. If it were not so, the LDS missionaries could not advise an investigator to pray and ask God – pointing out Moroni 10:4. If it were not so, Joseph could not have asked God relying on the promise of James 1:5. There is nothing special about the LDS admonishment, but it is a good, worthy and correct principle which all mankind ought to follow. If they do, no matter what their faith traditions, they will harvest the same results as those spoken of by President Eyring in the last LDS general conference.
Christ, however, can give the permanent gift of the Holy Ghost by His touch. (3 Ne. 18:36; Moroni 2:1-3.)
There are no “sealing” keys used by any Mormons in their temple rites: “Brothers and sisters, if you are true and faithful the time will come when you will be called up and anointed kings and priests, queens and priestesses, whereas now you are only anointed to become such. The realization of these blessings depends on your faithfulness.” It, like the Holy Ghost, is conditioned on your faithfulness. This same promise is made to all mankind by the Lord. (See, e.g., D&C 14:7; D&C 96:6; Alma 11:40; Moroni 7:41.)
Christ can and does seal a man up to eternal life. (See, e.g., Mosiah 26: 14, 20; Enos 1:5-8; D&C 132:49; 1 John 2:25.)
Institutions who use fear to control the hopes and aspirations of mankind concerning eternal life are in the gall of bitterness. Fear is of the devil. When the final remnant is gathered, they will have shepherds who remove fear. (Jeremiah 23:2-5.) When we are prepared by Christ, and by His word alone, we will not fear. (D&C 38:30.)
If we are warned we should warn others. But the Lord has instructed: “And let your preaching be the warning voice, every man to his neighbor, in mildness and in meekness.” (D&C 38:41.)
