Book excerpt: Welcome to the Orthodox Church—its history, theology, worship, spirituality, and daily life. This friendly guide provides a comprehensive introduction to Orthodoxy, but with a twist: readers learn by making a series of visits to a fictitious church, and get to know the faith as new Christians did for most of history, by immersion. Mathews-Green provides commentary and explanations on everything from how to “venerate” an icon, the Orthodox understanding of the atonement, to the Lenten significance of tofu. It’s the perfect book for inquirers and newcomers, but even readers who have been Orthodox all their lives say they learned things they never knew before. Enjoyable, easy-to-read, and leavened with humor, Welcome to the Orthodox Church is a gracious guide to the ancient faith of the Christian East.
