The Spirits of Form, third rank of the second triad, identified by Steiner with the seven Elohim of Genesis.
Exusiai in Anthroposophy are the Spirits of Form, third rank of the second triad in Rudolf Steiner's nine-hierarchy cosmology, identified by him with the seven Elohim of Genesis 1. Steiner systematized this teaching in Die Geistigen Hierarchien (The Spiritual Hierarchies, GA 110, lectures of April 1909 in Düsseldorf). On Old Sun the Exusiai sacrificed the germ of the human etheric body, and on Earth they stand as the form-givers proper, the beings whose sphere of power reaches up to the Sun and who shape the substance of life into bounded forms.
Their Greek name is Exusiai (Ἐξουσίαι); Dionysius the Areopagite called them Powers; the Hebrew tradition names them Elohim. Christ, in Steiner's reading, is the highest of the Elohim. Formative-force diagnosis at Klinik Arlesheim, in the Ita Wegman lineage, still reads illness as a disturbance in the shaping forces these beings sustain.
The Exusiai are the third rank of the second hierarchical triad, sitting between Dynamis (Mights, Spirits of Motion) above them and Archai (Spirits of Personality) below. Steiner places them as the form-givers in cosmic evolution. Their realm of activity reaches as far as the Sun, and their work is to bring the streaming substance of life into bounded, lawful forms that endure.
In Steiner's Own Words
The Elohim are those beings who remained connected to the Sun when the Sun separated from the Moon and Earth; they belong to the hierarchy called the Powers, Spirits of Form, and from there upwards to the hierarchies. They are still within our evolution. Elohim is the collective name for the Sun beings; at that time they had chosen the Sun as their dwelling place, not as their sphere of activity. Christ, the highest of the Elohim, is their ruler. However, he does not belong to the hierarchies, but to the Trinity. In Christ we have an entity before us that is so powerful that it has influence over all the members of our solar system.
What it Means Today
Anthroposophic medicine reads the body through a hierarchy of forces that work upward from physical substance into life, then into sensation, then into the I. The lowest of those, the formative or etheric forces, are the inheritance Steiner attributes to the Exusiai. At Klinik Arlesheim in Switzerland, the clinic Ita Wegman founded with Steiner in 1921, physicians in the Wegman lineage still diagnose chronic illness as a disturbance in the shaping forces that hold tissue, rhythm, and organ form together. The clinical method is observational and Goethean, not laboratory-first. The physician learns to read whether a kidney, a leaf vein, or a circadian rhythm has been overtaken by hardening tendencies or by dissolution, and treats with substances and rhythmic therapies meant to restore proper form.
What anthroposophy calls Spirits of Form is, in that clinical setting, not a metaphor but the highest of the working forces in a living body. The Exusiai do not appear; their work appears as the lawful, species-specific form of the human being. When a treatment at Klinik Arlesheim asks a patient to walk a particular eurythmic figure or take a particular mistletoe preparation, the working assumption is that human form is held together by beings whose sphere of power Steiner placed at the Sun.
