Not if you bother to READ what he wrote. He makes it clear that man can never attain true god standing. He makes it clear that the Father was never a man, but eternal.
Did you even read this from my post?
We are not begotten by God, we are only made by Him: in our natural state we are not sons of God, only (so to speak) statues.(Mere Christianity, p. 177)
Kinda shows that the definitions of any divinity within man is not equated to mormon doctrine. Read further about Bios, you will see further divergence. The specific quotes from CS Lewis are not mainstream Christian ideas.
And where do you get that idea? The words he uses may change, but the concepts of theosis and sanctification he speaks to ARE mainstream Christian ideas - far more than mormon.
Do all Christians ever agree on all doctrine? Hardly.
Yet Lewis' writings, if you've bothered to READ them, show that the attempt to selectively quote him and apply definitions that he himself would not use and in reality refutes later in even the same book places a gap between Lewis and mormons far greater than any disagreements within Christianity.
What you have always seem to overlook in our discussion as well as when Lewis is making a distinction between the Biological life and spiritual life.
Please read that passage carefully!
