Speaking in Tongues, Mar 26, 1830

-- Mar 26, 1830
The Book of Mormon, translated by Joseph Smith is published. It describes the gift of tongues as the tongue of angels, a gift given through the Holy Ghost. For example, see 2 Ne. 31: 13-14; Morm. 9: 7, 24; 2 Ne. 32: 2; Omni 1: 25; Alma 29: 8; 3 Ne. 29: 6. (1)

Joseph Smith translates Moses 6:2-19 as part of his inspired translation of the Bible:

Moses 1:5-6 And a book of remembrance was kept, in the which was recorded, in the language of Adam, for it was given unto as many as called upon God to write by the spirit of inspiration; And by them their children were taught to read and write, having a language which was pure and undefiled. (2)

[Ezra Booth] ... "Being carried away in the spirit" and "I know it to be so by the spirit," are well known phrases, and in common use in the Mormonite church. We will first notice the gift of tongues, exercised by some when carried away in the spirit. These persons were apparently lost to all surrounding circumstances, and wrapt up in the contemplation of things, and in communicating with persons not present. -- They articulated sounds, which but few present professed to understand; and those few, declared them to be the Indian language. A merchant, who had formerly been a member of the Methodist society, observed, he had formerly traded with the Indians, and he knew it to be their dialect. Being myself present on some of these occasions, a person proffered his services as my interpreter, and translated these sounds, which to me were unintelligible, into English language. One individual could read any chapter of the Old or New-Testament, in several different languages. This was known to be the case by a person who professed to understand those languages. In the midst of this delirium, they would, at times, fancy themselves addressing a congregation of their red brethren; and mounted upon a stump, or the fence, or from some elevated situation, would harangue their assembly, until they had convinced and converted them. They would then lead them into the water, and baptize them, and pronounce their sins forgiven. In this exercise, some of them actually went into the water; and in the water, performed the ceremony used in baptizing. These actors assumed the visage of the savage, and so nearly imitated him, not only in language, but in gestures and actions, that it seemed the soul and body were completely metamorphosed into the Indian. No doubt was then entertained but that this was an extraordinary work of the Lord, designed to prepare those young men for the Indian mission; and many who are still leaders of the church, could say, "we know by the spirit that it is the work of the Lord." And now they can say, "we know by the spirit that it was it is the work of the Devil." Most of those who were the principal actors, have since apostatized, and the work is unanimously discarded by the church. The limits, which my want of time to write, as well as your want of patience to read, compel me to prescribe for myself, will allow me only to touch on some of the most prominent parts of this newly-invented, and heterogeneous system. ...
