I remember hearing or reading about these.
They are fraudulent is all I remember. Sauce to part suckers from their money. On the level of fakery of the Mormon stuff
I saw a documentary about this and other “supposed” lost books of the Bible. They were fake. If you read them, you can see for yourself that they bear little resemblance to the Bible. I even looked them up after watching it several years ago.
Wait just a durned minute there! They have GOLD tablets from the angel Moroni! What other church has gold tablets from an angel?? Those gold tablets are proof. What's that . . . just where are those gold tablets? Now, who ran off with the gold tablets? Well, there's goes the proof. Well . . . nevermind.
