In what sense in the scriptures has the Lord Jesus Christ been referred to as an angel?
(Answer on page 13)
Here's answer to week's question
(From page 2)
The term angel means "messenger." Since the Savior is the "messenger of salvation" (D&C 93:8) and the "messenger of the covenant" (Mal. 3:1), the term could apply to Him in that sense, as in Jacob's reference to the "Angel which redeemed me" in Gen. 48:15-16.
