Again why doesn't the Bible use the Greek word for "first created"
(protoktizo), proto meaning first and ktizo meaning created, instead of
firstborn (prototokos) which seems to refer to a position of pre-eminence
rather than the order of birth?
Sorry, but you can only say this is isolation of the reference of Jesus being called "son". So whether he is first created or first born is not critical. Since the firstborn son, though, because of Jesus,was given special recognition, "firstborn" became LATER a reference to preeminence...not the other way around.
Had "first-created" been a reference to Jesus where the Bible would elsewhere not consider him the "son" of the "Father" then perhaps you could make that argument that it could not be a reference to his being the first of creation chronologically. But since that's not the case your emphasis is misplaced here.
The Bible makes many references to Jesus, many... Some might be misunderstood or easily taken out of context. But the vast majority of them are quite clear, that being clearly showing us the relationship between these two beings quite fundamentally as "Father" and "son". Any anxious relapse to misfocus on this will simply be a gross error.
Father....son
Father...first born son/first-created son...
Expand from here and you can't go wrong. Starting from somewhere else?
.....no guarantees.
