Tractatus de Ecclesia Christi

This is a 2 volume set. The first volume contains the major part of this work on the Constitution of the Catholic Church. It contains a section on the four marks of the Church, unity, holiness, catholicity and apostolicity. This is followed by a section on the members of the Catholic Church. It also considers schismatics and heretics and their relation to the Church. The second part of the first volume considers the powers of the Church, the power of orders and the power of teaching. Then there is a section on the Roman Pontiff. The first volume closes with a section on Ecumenical Councils. Volume two considers the relation of the Catholic Church to the world and civil society. This volume is much shorter. However, it contains a commentary on Apocalypse chapters 2 and three, which consider the seven Churches. These Churches are considered by some, such as Venerable Holzhauser and more recently Bishop Richard Williamson, as a history of the Catholic Church of seven ages.
