The Unification Church (popularly known as the 'Moonies') has been viewed as an eccentric and somewhat sinister 'cult', best known for the 'mass wedding' ceremonies conducted by its leader Sun Myung Moon. In The Advent of Sun Myung Moon George Chryssides remains critical of the movement, but brings the reader out of uninformed prejudice by presenting information about its Korean origins, its teachings and the many ceremonies which, until recently, remained undisclosed. The book is based on extensive conversations with members and critics alike, together with extended periods spent at UC seminars.
