Alister McGrath Explains What Christianity Offers that Secularism Cannot

Published Sep 23, 2026

Theologian, historian and apologist Alister McGrath joins Crosswalk Talk's Michael Foust to discuss his new book, Rethinking Christianity: A Thoughtful Guide to a Life-Changing Faith. McGrath explores why younger generations are showing renewed interest in Christianity and why he believes secular culture has failed to provide the meaning, purpose and stability many are seeking. He also discusses the impact of the COVID pandemic on questions of faith, why Christianity remains relevant after 2,000 years, and how Christians can better communicate the difference faith makes in everyday life. Plus, McGrath draws on his background as a scientist to explain why he believes science and Christianity are not enemies but can complement one another.
