Book excerpt: In this major collection, Rudolf Steiner affirms the reality of esoteric Christianity and unveils many of its secret teachings. His lectures are on the significance of the Mystery of Golgotha and of the Blood that flowed on the Cross; the relationship of Christ and Lucifer (or Love and Knowledge); the various paths of initiation, including the Christian-Gnostic and Rosicrucian Paths; and Steiner's early interpretations of St. John's gospel and the sermon on the mount. All of Steiner's lectures on the Lord's Prayer are also included, as well as the version of the prayer that Steiner himself prayed throughout his life. This is an excellent book for all those who want to deepen their understanding of the Western stream of Christian esotericism and Rudolf Steiner's approach to Christianity as a spiritual practice.
