The chicken came first.
Regeneration comes first.
Considering that we have no record of anyone making such a claim in the first two and a half centuries, and certainly nothing systematic or widespread for the first 16 centuries, I have my doubts both historically and biblically that this is a true statement.
I'm not aware of any mention of chickens in the Genesis account, but there is a reasonable probability that the chicken came first- though that just the logical inference if assumptions that the original objects of creation were all created as functioning adults are true. But these are merely assumptions, not verbatim facts!
There is equally nothing that explicitly says regeneration is the first event in the soteriological protocol. (And 1John 5:1 doesn't either from a grammatical pov!) Over and over again, believing is portrayed as the precipitous event immediately preceding being born again and receiving life spiritually.
no philosophical input necessary.
If there is no direct and explicit biblical evidence that says X is true then the argument is made from a logically derived implication, which is a philosophical construct, not a biblical theology construct.
