Definition: Aposthasis means "the apostles." It refers to the twelve or more, historically appointed apostles who were later removed from leadership roles due to various circumstances including conflicts with other apostles or by divine revelation. They typically lived in communities around the time they were chosen, preaching the message of Jesus Christ and forming a new community of believers. The term has been used metaphorically to suggest a group of people united under the influence of one person (in this case, Jesus).
