CS Lewis’ theology was often excellent, but he was not a theologian. He also didn’t preach a sermon. This is correctly termed an “Evensong message”.
Who cares?
It was a good message regardless of your holier-than-thou attitude.
He was a profound theologian who has won many souls to Christ abs inspired and taught generations of Christians
Fake news.

First time I've heard that phrase. Sounds like a Disney channel special.
I googled it and "Evensong mesage" is defined "a service of evening prayers, psalms, and canticles, conducted according to a set form of the Anglican Church".
So I'm pretty sure C.S. Lewis' advice wasn't an "evensong message", either.
