Now let's say that the capital letters were taken out, is there any doubt that Jesus is referred to as everlasting father?
I don't think there is doubt of that - disregarding proper translation/scribes, etc. But if Christ has been given all power and authority from God, His Father, then aren't titles included in that?
Note that He is not referred to as Almighty God. That could mean something. Just a thought.
