HMMMmmm...
An 1830 statement titled "Testimony of Three Witnesses"—one statement signed by three men rather than three separate statements—was published at the end of the first edition of the Book of Mormon:
Be it known unto all nations, kindreds, tongues, and people, unto whom this work shall come: That we, through the grace of God the Father, and our Lord Jesus Christ, have seen the plates which contain this record, which is a record of the people of Nephi, and also of the Lamanites, his brethren, and also of the people of Jared, who came from the tower of which hath been spoken. And we also know that they have been translated by the gift and power of God, for his voice hath declared it unto us; wherefore we know of a surety that the work is true. And we also testify that we have seeen [sic] the engravings which are upon the plates; and they have been shewn unto us by the power of God, and not of man. And we declare with words of soberness, that an angel of God came down from heaven, and he brought and laid before our eyes, that we beheld and saw the plates, and the engravings thereon; and we know that it is by the grace of God the Father, and our Lord Jesus Christ, that we beheld and bear record that these things are true. And it is marvellous [sic] in our eyes. Nevertheless, the voice of the Lord commanded us that we should bear record of it; wherefore, to be obedient unto the commandments of God, we bear testimony of these things. And we know that if we are faithful in Christ, we shall rid our garments of the blood of all men, and be found spotless before the judgment-seat of Christ, and shall dwell with him eternally in the heavens. And the honor be to the Father, and to the Son, and to the Holy Ghost, which is one God. Amen.
Oh, you mean like when Moses and Elijah appeared in person during the transfiguration?
Oh, for extra bonus points the Transfiguration, is the fourth decade of the Rosary on Thursdays (The Luminous Mysteries). You mull over each of the points in turn below during each successive "Hail Mary."
The Fourth Luminous Mystery
THE TRANSFIGURATION
1. Jesus took Peter, James and John up a high mountain to pray.
2. Jesus was transfigured before them.
3. "His face became as dazzling as the sun, his clothes as radiant as light."
4. This was to fortify their faith to withstand the coming tragedy of the Passion.
5. Jesus foresaw the 'scandal of the cross,' and prepared them for it by this manifestation of His glory.
6. Moses and Elias (representing the Law and the prophets of the Old Testament) were conversing with Jesus about His Passion.
7. "Do not think I have come to destroy the Law or the Prophets... but to fulfill them."
8. From a cloud came a voice: "This is my beloved Son, listen to Him."
9. Jesus admonishes them not to tell the vision to anyone until the Son of Man rises from the dead.
10. We too will behold the transfigured Jesus on the Last Day.
