The Word, God's Visible Image

[Costeon]

I have read a couple of Oneness books recently that teach that the Word before the incarnation was the visible image of God.(I believe I have read posts from Michael the Disciple on this forum teaching the same thing.) In heaven, therefore, there was always a visible form of God before the incarnation, and this form was the Word. And, if I understand this view correctly, the Angel of the Lord was the Word and not just a temporary visible manifestation of Yahweh. If you are familiar with this view, when the Angel of the Lord, i.e., the Word, appeared to someone on earth, was the visible form of the Word still in heaven as well?
