"The Angelic Defender of the Gnosis"

The Day of the Holy Saint Michael the Archangel, also known as Michaelmas, is an important feast day in the Gnostic liturgical calendar. The Archangel Michael has enjoyed a surprising prominence in all three of the great world religions of the West—Judaism, Islam, and Christianity. It was a day of particular importance among the feast days of the liturgical calendar of the Medieval Christian church, thereby obtaining the common name of Michaelmas. Of the three Archangels mentioned in the canonical writings of the Roman Catholic Church, none has enjoyed more popularity or had as many Churches and Chapels dedicated to him, as the Archangel Michael. His popularity and presence in the mystical dimension of the human psyche eventually forced the Roman Catholic Church to include him in their theology as a Saint.

The legends including him in the Christian tradition stems primarily from the story of his fight with the dragon in the Book of the Revelation of St John.
