The Priesthood Power of Women

Who has the privilege of the ministering of angels?

What does it mean that the Aaronic Priesthood holds “the key of the ministering of angels” and of the “gospel of repentance and of baptism, and the remission of sins”? The meaning is found in the ordinance of baptism and in the sacrament. Baptism is for the remission of sins, and the sacrament is a renewal of the covenants and blessings of baptism. Both should be preceded by repentance. When we keep the covenants made in these ordinances, we are promised that we will always have His Spirit to be with us. The ministering of angels is one of the manifestations of that Spirit. ("The Aaronic Priesthood and the Sacrament", Dallin H. Oaks, Oct 1998) 

... 

the ministering of angels can also be unseen. Angelic messages can be delivered by a voice or merely by thoughts or feelings communicated to the mind. President John Taylor described “the action of the angels, or messengers of God, upon our minds, so that the heart can conceive … revelations from the eternal world” (Gospel Kingdom, sel. G. Homer Durham [1987], 31). 

Nephi described three manifestations of the ministering of angels when he reminded his rebellious brothers that (1) they had “seen an angel,” (2) they had “heard his voice from time to time,” and (3) also that an angel had “spoken unto [them] in a still small voice” though they were “past feeling” and “could not feel his words” (1 Ne. 17:45). The scriptures contain many other statements that angels are sent to teach the gospel and bring men to Christ (see Heb. 1:14; Alma 39:19; Moro. 7:25, 29, 31–32; D&C 20:35). Most angelic communications are felt or heard rather than seen. 

How does the Aaronic Priesthood hold the key to the ministering of angels? The answer is the same as for the Spirit of the Lord.

In general, the blessings of spiritual companionship and communication are only available to those who are clean. As explained earlier, through the Aaronic Priesthood ordinances of baptism and the sacrament, we are cleansed of our sins and promised that if we keep our covenants we will always have His Spirit to be with us. I believe that promise not only refers to the Holy Ghost but also to the ministering of angels, for “angels speak by the power of the Holy Ghost; wherefore, they speak the words of Christ” (2 Ne. 32:3). So it is that those who hold the Aaronic Priesthood open the door for all Church members who worthily partake of the sacrament to enjoy the companionship of the Spirit of the Lord and the ministering of angels.

... 

The Aaronic Priesthood holds the keys of the “gospel of repentance and of baptism, and the remission of sins” (D&C 84:27). The cleansing power of our Savior’s Atonement is renewed for us as we partake of the sacrament. The promise that we “may always have his Spirit to be with [us]” (D&C 20:77) is essential to our spirituality. The ordinances of the Aaronic Priesthood are vital to all of this. I testify that this is true, and I pray that our brethren of the Aaronic Priesthood will understand the importance of their sacred responsibilities and act worthily in them, in the name of Jesus Christ, amen.
