An apostolicship is a term given for the office or tenure of a Pope.
There is no term "apostolicship" in traditional Christian theology or church structure. In Christianity, an apostleship refers to the role or office of an apostle, who is believed to be a chosen messenger of Jesus Christ. However, the term "apostolicship" may be used in certain charismatic or Pentecostal circles to describe the authority or spiritual oversight exercised by apostles within their respective networks or ministries.
