January 30 – “Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.” 1 Timothy 1:4
One of the most honored ways to attain true salvation in Mormonism is by performing works in the temples for the dead (usually your own relatives). The best way to do this is by going to the genealogical library in Salt Lake City, UT. There you will find literally millions of “pedigree charts” which are itemized lists of each relative and their vital stats which include date and place of birth, date and place of death, date of marriage and to whom, names and birthdates of children, et al. For a monetary fee they can have these printed out and take with them to the temples to be baptized, endowed, sealed and married by proxy for their dead relatives.
This is how dead people become Mormons.
D&C 124:28-40 tells the Mormons which buildings are to be used in order for them to be acceptable to the Lord. If they perform works for their dead while not in the temples, the works are unacceptable to him.
