The Adeptus Ministorum is in charge of expanding and monitoring planets to stay loyal to the ecclesiarchy and to the emperor. The Adeptus Ministorum, more commonly known as the Ecclesiarchy Guards, is the sole official state church of the Imperium of Man. It maintains and spreads the Imperial Cult throughout the Empire. Although the interpretation of particular Imperial Cult dogmas varies across the many worlds of the Imperium, any extreme deviance from its strictures and theology is considered heresy and dealt with with great severity by the Ecclesiarchy or, in extreme cases, the Ordo Hereticus of the Imperial Inquisition.
