The extraordinary volume unfolds a multifaceted picture of Christianity. It combines vibrant testimonies with clear thematic lines of concentration. For readers who wish to understand the historical impact and current perspectives of the formative force of our culture, the work offers a fascinating panorama. Hubertus Halbfas presents Christianity in a completely innovative way through the lens of historical testimonies. Instead of leading linearly through the ages, he repeatedly approaches the subject from varying questions to perceive as many layers as possible. Thematically differentiated longitudinal cuts such as church and state, war and peace, heretics, women, and charity allow for insights into trends, latent influences, directions, and issues. He addresses key areas that enable a closer examination of Christianity, its foundations, achievements, and teachings.
