The Apostles of Jesus Christ: Criteria, Mission, Role, and Function by Robert Alan King is a book with over 6,600 words. In this book, King discusses the calling of the apostles and the replacement of Judas after his betrayal as well as the criteria for the office of an apostle. He explores the apostle's mission, purpose and role for Christ. In addition, the book examines passages that use the Greek noun apostolos (apostle) for others besides the 12 and determines if they are being called apostles in the strict sense of the term or if it is being used in a loose way that simply conveys the proper meaning of the Greek word as being sent from someone or somewhere as an envoy or representative. In addition, the study will explain why the apostolic office was exclusively designated for the beginning of the church, becoming obsolete after the death of the 12 apostles. Robert Alan King is an ordained minister through Calvary Chapel.
