Revolution
A heretical Talmidim priest by the name of Adrian Kevi believed that those affected by the Stigma VIRUS had souls and led a split in the denomination.
Adrian Kevi, a Sadducees Talmidim Archbishop preaches that he was told by Adonai that non-human races have souls. Believing this to be a remark on how the Church handled the De Anima Crusade, he preached a tone of reconciliation. Eventually, this led to a crackdown by The Curia and he was stripped of his ecumenical rank and executed. However, despite this harsh treatment, numerous Keviites can be found and the Church ensures the diplomats sent to other factions they deem non-human are a Keviite.
