I think Bullinger makes a good argument and that the preponderance of the evidence is heavily on the side of his thesis being true.@Clete You have also referred me to the Witness of the Stars by Bullinger. I have already read this and I think I am on the same page as your as far as this is concerned. But there is NOTHING in the Bible that directly supports any of this. God only tells us the meaning of 1 star in the Bible (IIRC) and there is nothing in the Bible that says the head of the egyptian sphinx represents His virgin mother. There is nothing in the Bible that even comes close to saying anything like that. But you believe it. So do I.
Not all truth has to come out of the bible but there is no such actual thing as a contradiction. The bible is truth and so any truth claim, particularly a theological one such as what Bullinger puts forward, must be consistent with the bible. I see nothing in Bullinger's teaching that is inconsistent with God's word.
