Sometimes a customer review says it best:
“David, Thank you so much, I truly love your interpretation of CS Lewis. I am currently taking a free online course from Hillsdale College on CS Lewis. When I first started reading his books, I did read the entire book, but felt like a middle-aged intellectual boob. What was I thinking that I could even complete a course like this with such a deep philosophical author?
I wondered how many times I would have to re-read the book, or how many trips to my online dictionary I would have to make, till I understood the full philosophical work in the book. Then, out of sheer luck, I was scrolling the web and YOUR books popped up. So I searched to find one and vavoom, I understood.
You were God sent!!!!! And I mean that with all my heart. I was so frustrated with the words and just the lack of Everyday English that I was almost ready to give up on the whole endeavour of becoming a more educated person in his writings.
Thank you again for taking the time to write these books so folks like me could have a greater understanding.” D. C.S. Lewis’ Mere Christianity in Everyday English
C.S. Lewis’s Mere Christianity is recognized as one of the most persuasive works of Christian apologetics in the twentieth century. Yet its mid-century British idioms can be a barrier for modern readers.
In this edition, David O. Harrison faithfully renders Lewis’s arguments in clear, contemporary English, allowing Lewis’s logical precision and theological insights to shine without distraction. Harrison’s own journey—from skeptic to believer—mirrors Lewis’s, making him a natural guide for today’s audience.
This reworking preserves the intellectual rigour and timeless wisdom of Lewis’s original text while making it accessible to students, seekers, and serious readers alike. More than seventy years after its initial publication, Mere Christianity remains a timeless challenge to minds and a transformative influence on lives.

I was concerned that a re-write / update might change the original intent of CS Lewis but it does not. Just makes it flow nicer for easier reading in modern English!

If you love C.S. Lewis but have a difficult time understanding some of his archaic language, you need this modern English version by David Harrison. Mr. Harrison takes the language of mid-twentieth century England and gives it an update making Lewis more understandable and enjoyable to the modern reader. A great read.

I am so impressed Mr. Harrison has done what I wish had been done before. He took a marvelous work that, for some folks, like myself, can be lost in the language used in some parts of the book. Lewis’ Mere Christianity & The Screwtape Letters have a profound message that people like myself can get a better understanding by rewording parts in a more modern vernacular that can be absorbed deeper both mentally and spiritually.
Thank you Mr. David Harrison. Well done sir!

Thank you for writing this version. It’s so easy to read and understand. I have the original as well but found it hard to understand certain portions of the original text. Thank you again Mr David O Harrison.

Excellent read for those wanting to learn more about CS Lewis and/or his take on being a Christian. It being translated into modern/everyday English makes it an easy read and far easier to understand what he was saying/meaning. I also recommend The Screwtape Letters by CS Lewis and The Pilgrim’s Progress by John Bunyan who greatly influenced Lewis.
