Angels are created beings, created during the six days of creation. As the eternal Son of God, Jesus was involved in their creation (John 1:1-3). Rather than being an angel, Jesus created the angels.
What can confuse people, I imagine, is that the Bible sometimes calls Jesus “the angel of the Lord.” When he appeared to people before he took on human flesh at his birth at Bethlehem, the Bible calls Jesus “the angel of the Lord.” Genesis 16:7-16 is one of those sections in the Bible that describes such an appearance.
What can eliminate that confusion is keeping in mind that the basic definition of “angel” is “messenger.” When Jesus appeared to people prior to his incarnation, he brought messages concerning God’s plan of salvation—that centered in him.
