The LDS Church currently teaches they have the fulness of the temple ordinances and all that God intended to reveal on the subject. Again, I totally disagree. The LDS Church did not previously believe or teach they had the fulness of the temple teachings. That is a recent claim and is simply not true.
Communication systems have failed. There is no cellular network. There is no central government, either on a national or state level. There is no police force, no military. No fuel for the fighter jets and tanks. Our great health care system with all the hospitals, medicines and lifesaving power has been decimated. Distribution of goods is non-existent. Civilization has gone back a hundred and fifty years. No cars, no working sewage systems, no more water distribution.
