The Omnissiah is a central religious figure within the Cult Mechanicus.

欧姆尼赛亚是机械教派中的核心宗教人物。

According to the faith of the Adeptus Mechanicus, the Omnissiah is the physical manifestation of the Machine God and part of the trinity which includes the Machine God and Motive Force. Members of the Mechanicum frequently invoke the blessing of the Omnissiah and plead for His aid while undertaking technological activities. The Adeptus Mechanicus dictates that the Emperor of Mankind is the Omnissiah, linking the Cult Mechanicus with the Imperial Cult. The Emperor first appeared to the Mechanicum on Mars in the early Great Crusade, displaying apparent technological miracles such as repairing a Knight with a touch. Ultimately it succeeded to convince the Tech-Priests to believe in his divinity.

根据机械神教的信仰，欧姆尼赛亚是万机神的物质显示，是包括万机神和源力在内的三位一体的一部分。机械教的成员在从事技术活动时经常祈求欧姆尼赛亚的祝福并恳求他的帮助。机械神教规定，人类帝皇是欧姆尼赛亚，将机械教派与帝国教派联系起来。在大远征早期，帝皇首次出现在火星上的机械教面前，展示了明显的技术奇迹，比如用触碰修复骑士。最终，他成功地说服了技术神甫相信他的神性。

Not all members of the Mechanicum have believed that the Emperor is the Omnissiah. Most infamously, Fabricator-General Kelbor-Hal during the Great Crusade was skeptical of it and saw the Emperor as a false prophet. This doubt ultimately helped contribute to the Schism of Mars during the Horus Heresy and the formation of the Dark Mechanicum.

并非所有机械教成员都相信帝皇是欧姆尼赛亚。最著名的是大远征期间的铸造将军凯尔博·哈尔对此持怀疑态度，并将帝皇视为假先知。这种怀疑最终促成了荷鲁斯叛乱时期的火星分裂和黑暗机械教的形成。

One of the surviving Men of Iron, UR-025, states that it has met the true Omnissiah, not the false one worshipped by man, and that it would find the Mechanicum disappointing.

其中一位幸存的铁人UR-025表示，它遇到了真正的欧姆尼赛亚，而不是人类崇拜的虚假的欧姆尼赛亚。
