Well, that's depend on topic.
But Celes already said like that, ("little jokes"), mean she already know that's will be happened (furthermore, refer for Ch. 1, for making sure that the power of the real Goddess)
For that world's native humans, they are both Goddess (refer to Chapter 3-5, part of her being called "Goddess", and this Chapter for people reactions)
Well, indeed she is Immortal.
Furthermore, with the unlimited power of creations skill were one of God-like power obviously (read as "cheat").
And well, if there was a sparring match, Kaoru's power and ect were a little behind of Celes (with involving of freedom potion maker power) but, when in another terms, Kaoru has advantage from Celes too.
That's no way it could be more distance from God-like.
