"Christmas carols are a special feature of the season. They bring feelings of joy to our hearts as they describe the events and significance of the birth of Jesus Christ. It is interesting to note that many Christmas hymns speak of angels. This is because the biblical record contains numerous accounts of heavenly beings speaking to mortals before and at the time of His birth. An angel announced His pending birth to the young woman Mary and to Joseph, her espoused husband (see Luke 1:26–33; Matthew 1:20–21). An angel accompanied by a heavenly choir heralded the birth to the shepherds in the fields (see Luke 2:8–14), and angels kept watch over the family during the early years when Herod tried to destroy the young Jesus (see Matthew 2:13, 19–20). Not only is the story of the Savior’s birth replete with heavenly messengers, but heavenly beings were also present at significant events throughout His life."
"One might ask, “Why were angels so prominent at the Savior’s birth? And why were they such an important part of His life and ministry?” The answers are twofold. The first pertains to the nature and mission of the personage whom they were heralding—a divine Being, the Son of God, the Only Begotten in the flesh who came to earth to save all of God’s children. The second concerns the ushering in of a new dispensation, a period of time when the gospel would be restored in its fulness. The ministry of angels is to assist in the ushering in of dispensations (see Moroni 7:29–31)."
