Even if an angel of the Lord has a personal name and the whole story is both literal as well as symbolically pointing to literal events to take place? Specifically the events of Christ's atonement?
Ie serpent biting the heel of a faithful servant cleansing himself in the water, an angel of the Lord as man prompts the servant to take on this monstrous serpent and loosen him unto it's belly from the hostile waters, the bait of the sinful serpent overrides the serpent having in its place a harmless fish suffocating and dying and putting out the old beast, the heart of its center is consumed by fire, the toxins passing through its liver are given up all at once and refined through flames, together they fill the temple of the house of the faithful with it's glory and drive out demons as if it were the most fowl stench to them.
The gall holds proclamation of faith to heal and anoint the blind.
The flesh and blood is taken as food.
The "fish" is now a fisher of man, Christians.
Early Christianity used the fish symbol for Christ... coincidence??
Literal? yes, symbolic? yes, obscure? yes
Why else would a demon run away from fish guts unless it knew who it was pointing to... He who is coming soon, He who has the power to cast demons out of the faithful and believing of him, the NAME is why it ran.
Even IF it were that Josiah? Would you still compare it to the cat in the hat?
