The second book, "The Paths of Christianity," covers the first millennium AD. It outlines the spread of Christianity, the missionary activities of the disciples of Jesus, the first Christian Empire, the Church Fathers, the causes of the Great Schism, and the Baptism of Russia. The author reveals the mystery of thousands upon thousands joining the Church through love—the mystery, without which one cannot understand the profound transformative power of the Christian movement on humanity. At the same time, Alexander Men does not idealize Christianity—he shows the real picture of the Church's life, without glossing over its dramatic sides: dissenting views, schisms, heresies, and outbursts of fanaticism. The author's moral principles compel him to present a fair and unprejudiced account of these topics.
