The Book of Mormon testifies of the authenticity and purpose of angels (see Alma 13:22–26; 32:23; 3 Nephi 17:24; Moroni 7:29–31; D&C 20:10). In reference to the reality of angels, Elder Jeffrey R. Holland of the Quorum of the Twelve Apostles said:
“I am convinced that one of the profound themes of the Book of Mormon is the role and prevalence and central participation of angels in the gospel story. …
“One of the things that will become more important in our lives the longer we live is the reality of angels, their work and their ministry. I refer here not alone to the angel Moroni but also to those more personal ministering angels who are with us and around us, empowered to help us and who do exactly that (see 3 Ne. 7:18; Moro. 7:29–32, 37; D&C 107:20). …
“I believe we need to speak of and believe in and bear testimony of the ministry of angels more than we sometimes do. They constitute one of God’s great methods of witnessing through the veil, and no document in all this world teaches that principle so clearly and so powerfully as does the Book of Mormon” (“For a Wise Purpose,” Ensign, Jan. 1996, 16–17).
