To Tell the Truth…or Not 

D&C 19:31, 37; “And of tenets thou shalt not talk, but thou shalt declare repentance and faith on the Savior, and remission of sins by baptism, and by fire, yea, even the Holy Ghost.  And speak freely to all; yea, preach, exhort, declare the truth, even with a loud voice, with a sound of rejoicing, crying—Hosanna, hosanna, blessed be the name of the Lord God!”

Revelation given in Manchester, NY in March 1830.  History of the Church 1:72-74. 

See D&C 42:12; “And again, the elders, priests and teachers of this church shall teach the principles of my gospel,..” 

Are the missionaries and other members of the Church not to teach others what they believe in or not?  Growing up in Mormonism I knew there were secret (Mormons call them sacred) oaths that are taken out in the temple.  However, someone like my husband Kirk knew nothing of that when he joined the Church.  In fact, Kirk didn’t know a lot about the Church until after he joined which is true for most if not all converts of Mormonism.
