Apostolic refers to something related to or associated with an apostle. An apostle is a person who is sent on a mission, especially one of a religious nature, and it comes from the Greek word “apostolos” which means messenger or envoy. In Christianity, the term "apostolic" often refers to the early followers of Jesus Christ, known as the twelve apostles, who were sent out by him to spread his teachings. The word can also be used in a broader sense to describe any group or individual that carries on the mission and legacy of an apostle or founding figure. In this context, it may refer to a religious organization or movement that claims descent from the early Christian church and its teachings.
