Definition
Omnissiah is the Cult Mechanicus’s name for the Machine God — the divinity in whom all data, all motion, and all causation are perfected. The Cult holds that the Omnissiah is the source of all knowledge and that to acquire knowledge is to approach divinity.
Per the Treaty of Mars, the Cult formally accepts the God-Emperor of Mankind as a manifestation of the Omnissiah, while in private rite the two remain distinct theological entities. The accommodation is doctrinal, not metaphysical.
Aspects
- The Motive Force — that which animates, fundamental cause of all action.
- The Machine Spirit — the localised will of any sufficiently complex device.
- The Sacred Pattern — the geometry of sanctioned designs (STC).
- The Quest — the imperative to know.
Liturgical practice
Worship is not contemplative but operational. To service a machine — to clean, to oil, to recite the cant of awakening, to perform the prescribed diagnostics — is the prayer. Failure of a machine is treated as a moral failing of the priest first, and a fault of matter second.
