The term “angel” in the Bible typically refers to a higher-order, personal spiritual being created by God.
However, there is one “angel” who is exceedingly unique: He not only acts with divine authority but also speaks in the voice of God, and is described in ways that align with God's own identity (see Exodus 20:21-23; Exodus 33:2; Exodus 33:14-15; Numbers 20:16; Joshua 5:13-15; Judges 13:6, Judges 13:21-22).
According to Colossians 1:15, we have ample reason to believe that this extraordinary “angel” is in fact the second person of the Godhead—Christ Himself (see also 2 Corinthians 4:6; Hebrews 1:3).[1]
