Angels

Who, my friends, are angels, these beings we have read about in scripture? And what is their purpose? Angels serve God in heaven, therefore their work is in ministering to the children of men on earth.

Angels have appeared in times past, and they still appear, and will always appear, so long as there are those with strong faith. Speaking of the last days, John the beloved wrote:

"And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people," - Revelation 14:6

An angel, Moroni, a resurrected being, appeared to the prophet Joseph Smith to guide him to obtain and translate the gold plates, which translation became the Book of Mormon. Moroni stands atop the temples of Christ's Church, sounding the trumpet to announce the restoration of the gospel.

If we are faithful, we may one day become angels like Moroni. And even in this life, Christ calls us his "saints" if we follow him and are baptized, as is shown in the title of The Church of Jesus Christ of Latter-Day Saints. we can both learn as though from angels and teach with the tongue of angels:

"Do ye not remember that I said unto you that after ye had received the Holy Ghost ye could speak with the tongue of angels? And now, how could ye speak with the tongue of angels save it were by the Holy Ghost?
"Angels speak by the power of the Holy Ghost; wherefore, they speak the words of Christ. Wherefore, I said unto you, feast upon the words of Christ, for behold, the words of Christ will tell you all things what ye should do." - 2 Nephi 32:2-3

Relevant notes:
-On the topic of the name of the Church: Christ revealed to his ancient disciples in the Americas that the church, if it taught his gospel, ought to be called in his name. (3 Nephi ##:##) In the Doctrine and Covenants, Christ revealed to Joseph Smith that the name of his modern church should be: The Church of Jesus Christ of Latter-Day Saints. (D&C ##:##)
-Angels, we have learned in modern revelation, look like men because they are, in fact, either the "spirits of just men made perfect" prior to their resurrection, or otherwise they are postmortal, resurrected men. (D&C 129:1-3) Also, "there are no angels who minister to this earth but those who do belong or have belonged to it." (D&C 130:5)
-The wings of angels, I take personally as a beautiful, poetic metaphor for the power, grace, glory, etc. of these heaven-sent beings. God himself is described metaphorically in Ruth, Psalms, and Malachi as having wings, and men too in Isaiah 40:31.
