Dr. Thiel continues the series of going through answering questions that were commonly posed to the old Worldwide Church of God. Using a binder that many speakers were given by that church that contained standardized letters that were sent to answer questions, Dr. Thiel answers them. Normally, in much greater detail than the normally single or double page answers that were given in the past. Subject covered included the 'Jubilee year,' economic restraints, aspects of the calendar, areas of the Book of Revelation, and the origin of the cross.
The two topics covered in most depth which written materials are also available are the articles "The Day of Atonement--plus the Jubilee" URL: http://www.cogwriter.com/atonement.htm and "What is the Origin of the Cross as a 'Christian' Symbol?" URL: http://www.cogwriter.com/cross.htm
