This companion reveals Rudolf Schwarz to be one of the greatest theologians of the twentieth century. As a German architect and mystic he created some beautiful churches in a stripped-down 1930s-Modern style, but he is most revered for a single book-in English translation The Church Incarnate. In it he explores the relationships between God and God's people, relationships expressed when they meet together in worship. Schwarz is revered for his spiritual insights but it is sometimes hard to follow him on his mystical wanderings. This companion accompanies him on his sacred journey, gently guiding him back on track when he wanders off-course and keeping him cheerful. This journey has had a surprising outcome: a discovery that, embedded in its union of earth and heaven, is a practical and logical structure for the renewal of the church; renewal of its worship, space, and its ministry. Already several congregations seeking renewal have used these concepts to find clarity and direction for their own sacred journey into the future.
