@PeterTurner After reading the book some more, I can now see how CS Lewis notion of happiness (labeled as "hedonist" but a moral one) is very different than Aristotle & Aquinas (labeled as "eudaimonist"). It takes a philosophy professor to point out the differences; even the famous theologian Alister McGrath (who also wrote a book on CS Lewis) misrepresented CS Lewis on this topic. Now I need to decide which theory of happiness (and its link to morality) I want to choose for my own !

@curiousdannii After understanding CS Lewis theory of happiness better, I feel that he is quite aligned with John Piper who tags himself a Christian hedonist. Once Prof. Goetz shows me how Aristotle theory of how virtue is linked to happiness is against common sense, it really surprised me since Aristotle is known as the philosopher of common sense.

About how C.S. Lewis wants to remain Anglican, I learned from the book that C.S. Lewis was under the false impression that to be Catholic requires acceptance of Aquinas's key teachings. At that time Thomism was heavily promoted after the 1879 Aeterni Patris with the attendant scholasticism which C.S. Lewis hated. It's a different climate now which should have appeased C.S. Lewis although the difference of happiness is still there.

@GratefulDisciple that's a happy decision to make, probably a win-win. Is there a reason you can't choose both?

@GratefulDisciple How the wording of the Nicene creed was determined, I was surprised by when reading my daughter's history book. Are you talking about how Constantine kind of forced some of those decisions?

@GratefulDisciple But if you've gotten through that without a strong understanding of why Catholics defend Jesus' humanity and Divinity you should make a pit stop at the council of Ephesus catholic.org/mary/maryc.php
