Theophanies are ways God shows Himself to physical man, so God came often in a form people could see and hear. Yet, it is true also that no man has seen God with his/her physical eyes for God is immaterial, a/the Spirit. Good questions. I didn't want you to get lost on this page so perhaps Rosen will pick up or this will be enough.
Agree, the Father is not the Son. I'm not a tritheist. Rather, somehow God is conveying distinction yet has told us He is only one God where none else are after Him or before. The only thing a Trinitarian want's to do at that point, is believe both sets of truth and leave it there. Any 'figuring it out' would be speculation unless the scripture spells it out plainly. Imho, then, the triune view sees only one God. Father Spirit and Son are Him. How? :idunno: I'm just trying not to second guess scripture. I can give 'speculation' where scripture is silent but we mostly just want people to know what scripture says and embrace scripture truths as-is similar to what Rosen said:
I'll let Rosen pick up from here as needed, again just didn't want to see you get lost in the shuffle because I think they are good inquiry questions. -Lon
Some questions I came up with while attempting to find "explanations" for how some of this could work. Here's some of my thought processes:
Question; Is God powerful enough to exist in more than one place at a time?
Answer: I can exist in four states of the Union at once if I stand on the right place. God is bigger than I am.
Question: Can God exist in heaven above and walk on the earth below at the same time?
Answer: I can place my hand inside a hamster cage with the hamsters while existing outside the cage (their world) at the same time. God is more grand compared to the earth than I am to the hamster cage.
Rhetorical: Is God powerful enough to know all things knowable? We will assume yes.
Question: Is God powerful enough to be able to exclude what could be known to the extent that he could play a fair game of cards, for example?
Answer: I would assume yes. All powerful can overrule all-knowing.
Question: Can God operate "fairly" in an instance where he needs to act as if excluding information known while at the same time accessing that information in another manner?
Answer: I would assume yes.
Question: Could God then operate with limited knowledge and power as Jesus while acting with full power and knowledge in heaven above?
Answer: I would assume yes.
Question: What determines whether God is God? If God restricts his power or knowledge in some fashion for a purpose, is he no longer God?
Answer: I consider the heart and character of God to be his true definition of himself.
Answer: In another sense, "God" is also a title that belongs to a person, rather than the person himself. In that aspect, if God operates outside the role of "God" he is not "God" in that sense, yet being the same person.
Question: Would it be out of character for Jesus to act out a role and allow us to operate under bad assumptions should we make them?
Answer: It has happened from time to time. Why did he appear in a different form on the road to Emmaus? See Luke 24:32
Answer: "Lamb of God" and "King of Kings" are different roles as well. One is the sacrifice for our sins and the other our returning triumphant king.
Answer: Was John going to live until the return of Christ? See John 21:23.
My point is that we should determine what scripture says first and then adjust our viewing angles to accommodate the hard sayings, rather than the other way around. There is enough evidence to show that Jesus was God, the One God, as the bible both says and intimates this. Instances where Jesus acted as if he were a normal man are explainable by circumstances. When you combine the two, "being God" takes precedence because otherwise it would be blasphemy.
