Why do you limit God?
Why do you limit Christ, the Second Person of the Holy Trinity?
Could not Christ have appeared as an angel?
I’m not limiting anyone, much less the Lord. He can do as He pleases. Our finite minds cannot fully grasp Him at this time. He speaks to us in ways we can understand. I take Him at his Word. When He describes a creature as an angel of the Lord, I believe Him, and I try NOT to OVER-THINK things unnecessarily. You can, you know.
