Divine Mission of Joseph Smith
Doctrines of Salvation 1:188; “If Joseph Smith was a deceiver, who wilfully attempted to mislead the people, then he should be exposed; his claims should be refuted, and his doctrines shown to be false, for the doctrines of an impostor cannot be made to harmonize in all particulars with divine truth. If his claims and declarations were built upon fraud and deceit, there would appear many errors and contradictions, which would be easy to detect. The doctrines of false teachers will not stand the test when tried by the accepted standards of measurement, the scriptures.” – Joseph Fielding Smith
First of all many errors have been shown to prove Smith was a deceitful man who went out of his way to defraud people and God.
These words by his nephew are nothing but a clanging symbol.
