Joseph Smith was not an Apostle of Jesus Christ. If he had been, he would have been mentioned in the Bible.
And martyred.
Thank you.
There were only Twelve Apostles who were witnesses to Christ’s earthly ministry and who were able to write the Word of God as witnesses.
Joseph Smith was deceived by a demon disguised as an angel of light, who deluded him into thinking it was okay to besmirch and rewrite the Eternal Word of God.
Smith broke with Scripture so many times, it is scary. But the first clue was that he was a Mason, and bowed the knee to another, Satan.
