Inspired by a friend to examine his personal philosophy on religion, G. K. Chesterton walks readers through his conversion to Christianity, which was based on a rational consideration of fact. Orthodoxy considers the logical and scholarly arguments in favor of the Christian faith and presents an impassioned argument for the church as a positive, liberal organization. One of the strongest apologias ever written, it is a critical triumph from a renowned author, poet, journalist, and philosopher, whose own spiritual journey provides the foundation for this fascinating treatise on religious belief.
