Curtiss Frank Homer and Harriette Augusta

Harriette Augusta and Frank Homer Curtiss established The Order of Christian Mystics in 1908, initially named The Order of the Fifteen. This spiritual group aimed to present advanced Christian mysticism to the Western world, drawing from Western mystery school traditions and Theosophy. Their teachings, transmitted through Harriette from Helena Petrovna Blavatsky, were disseminated via correspondence, publications, and lectures, reaching thousands globally. The Order focused on personal spiritual regeneration, or spiritual alchemy, through practices like prayer, study, and meditation, offering a Western-centric approach to mysticism.

Their extensive published works, authored primarily by Harriette, sought to interpret Christian teachings and the Bible through a mystical lens. The Curtiss's also founded the Church of the Wisdom Religion, which later became the Universal Religious Foundation. Harriette, a former writer and musician, developed clairvoyant abilities and became a central figure in occult teachings. Frank Homer Curtiss continued his healing practice and mystical work after Harriette's passing, eventually remarrying and passing on the legacy.

The Order of Christian Mystics was established in 1908 in Philadelphia by Harriette Augusta and Frank Homer Curtiss. Originally known as The Order of the Fifteen, its primary goal was to introduce advanced Christian mysticism rooted in Western esoteric traditions to the Western world. The Order's teachings were significantly influenced by Helena Petrovna Blavatsky, founder of the Theosophical Society, with Harriette acting as a conduit for these teachings. The core philosophy emphasized personal regeneration and spiritual alchemy, advocating for the transmutation of creative energy through spiritual practices such as prayer, devotion, study, and meditation. This approach was designed to be compatible with Western cultural and psychological frameworks, offering a reinterpretation of earlier mystical traditions like Rosicrucianism and Gnosticism.

The Order's teachings reached a wide audience through a robust system of correspondence, extensive book publishing, and public lectures delivered across numerous centers. Their outreach extended to over 70 countries, with a significant focus on the American esoteric community, whom they believed would lead in Western mysticism. The Curtiss's produced over 27 books and publications, with Harriette being the primary author. Key works include 'Letters from the Teacher' (1909), 'The Voice of Isis' (1912), and 'The Message of Aquaria' (1921), which served as foundational texts. They also addressed contemporary issues through works like 'The War Crisis' (1914) and explored universal laws in 'The Key to the Universe' (1915) and 'The Key of Destiny' (1919).

During World War I, the Curtiss's founded the Church of the Wisdom Religion, a more inclusive organization than their initial order. This entity was later incorporated as the Universal Religious Foundation in 1929 after the couple relocated to Washington, D.C. Harriette Augusta Curtiss, known within the order as Rahmea, passed away in 1932. Dr. Frank Homer Curtiss continued his healing practice, incorporating holistic methods and radionics alongside mystical teachings, until his death in 1946. He remarried and his second wife, Eleanor Chapman Stevens, continued his work and likely preserved the Order's archives. The combined works of the Order were made publicly available in 2009.
