The Biblical Unitarian (BU) perspective on the pre-incarnational existence of the Son of God, revealed in such verses as John 1:1-2
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God.
is that this pre-incarnational existence was a notional existence. A Biblical Unitarian website describes notional existence as opposed to literal existence as follows:
Notional pre-existence is the idea that something or someone may ‘exist’ in the mind of God before actualizing on earth in history at the appointed time. What God purposes and decrees is considered so certain that it is spoken of as though it already exists.
My question is regarding to what degree Biblical Unitarians carry "notionalism" throughout John's prologue. For instance, if we parenthetically add (notional) to John 1:1-2 it would look like this and, from what I understand, BU would agree:
In the beginning was the (Word/notionality), and the (Word/notionality) was with God, and the Word (notionally) was God. The same was (notionally) in the beginning with God.
Can verse 3 be rendered in similar fashion: Were all things only notionally created through him?
All things were (notionally) made by (the notional) him; and without (the notional) him was not any thing (notionally) made that was (notionally) made.
Can verse 4 be rendered in similar fashion: Was it only a notional life that was the notional light of men?
In (the notional) him was (notional) life; and the (notional) life was the (notional) light of men.
Can verse 6 be rendered in similar fashion: Did the notional light only notionally shine in the darkness?
And the (notional) light (notionally) shineth in darkness; and the darkness comprehended it not.
I don't know if I should ask whether the darkness and the non-comprehension are notional as well but the above questions are only intended as illustrative.
Ultimately, I am asking if Biblican Unitarians believe that the notional idea of Christ, the Son of God includes not just God's idea of an individual who is to come but also the creation, devastation, and reconciliation of everything through that individual.
In other words, Does everything God has ever thought have notional existence within Logos as long as it remains as His thought? For example, Did light exist notionally prior to God speaking? and, if so, did it exist notionally within Logos?
