I’m sure we have a lot of common ground, but I’m not sure this is where we’ll find it. I’ll work my way down the list, but I may not hit everything …
I’m going to stop you right there. (Surprise! haha) If we consider the image of God a vocation, then we can’t really speak of people as “Image Bearers.” That is confusing the substantialistic view, which considers the image as something inborn (part of the “stuff” that makes us human), with the functional view, which sees the image as a purpose or calling. Because of mankind’s fall into sin, we are unable to function properly as the image of God. In relational terms, no one loves God or others as we should, and in functional terms, no one truly represents God’s goodness, justice, and mercy. So, I agree with you that humanity must possess certain capabilities in order to function as God’s image, but I don’t think that possessing those capabilities makes one an Image Bearer, just as having the capability to be a doctor does not make me a doctor. See what I mean?
The distinction you’re trying to make is not applicable if the image of God is a vocation, and the requirement that humanity had a “sharp” beginning in time is entirely arbitrary. As well, the equation of “time T” with God making the human body in his image again conflates the substantialistic and the functional interpretations of the image.
Again, this confuses possessing a human body with the image.
On No. 5, the Son of God is definitely the paradigm for all mankind, but all you’re saying here is that God planned to arrive at his desired destination, which was the incarnation of the Son of God. I don’t think anyone would take issue with that.
I’m going to stop with No. 6, though, because it is a good example of why I think your treatment is flawed. Namely, you are treating the image of God as if it were an “observable anatomical feature,” which is fundamentally wrong, and you use it this way in order to distinguish “human” from H. sapiens and previous hominins, which is completely irrelevant to the biblical narrative.
