Written by divine revelation, this book teaches the theological doctrine of the Church (ecclesiology). It also contains prophecies that call for a reform in the modern Church. This way, this book helps Christians to understand the Church better, and also put before their eyes prophetic messages that God says to the last-days Church. The book is honestly written by an author who God has spoken to by His Spirit, and sent to teach the whole Church. This volume is the second edition of the book.
