'Orthodoxy' details Chesterton's search for his own personal understanding of Christianity, free of the chains of religious dogma. "The modern world is full of the old Christian virtues gone mad. The virtues have gone mad because they have been isolated from each other and are wandering alone."

'Orthodoxy' describes Chesterton's discovery of faith – a journey which is compared to an English adventurer who gets lost and unknowingly, discovers England all over again. Here he is doubly blessed, enjoying both the excitement of exploration, and the security of being home. Again, modernist blind spots are exposed, as the reader is invited into 'the thrilling romance of Orthodoxy...there was never anything so perilous or so exciting.'
