Towards the end of his life, Rudolf Steiner published a series of weekly letters addressed to the members of the Anthroposophical Society. Among them were fourteen letters in which he described the mission of the Archangel Michael, the mighty spiritual being who has accompanied humanity's evolution from primordial times right down to the present day.

In this insightful book, Charles Kovacs draws on his knowledge of Steiner's work to provide a deeper understanding of the history and ideas that inform each letter. He shows how the Archangel Michael is the great champion of human freedom in the modern age and how he can help us transcend divisions of national identity to embrace a truly universal view of humanity.
