The fourth chapter deals with Calvinist professions of faith from the first (the 1557 Hungarian Confession) to the last (the 1647 Westminster Confession of Faith) eighty years later.
The fifth chapter deals with the importance of the Westminster Assembly. For it was this, probably the greatest meeting of theologians in the history of the world, which gave us our own Subordinate Standard.
The sixth chapter deals with that fallible and amendable Subordinate Standard. There, the Westminster Confession of Faith is briefly summarized.
The seventh chapter gives a brief history of the unamended Westminster Standards in Australia, before Union in 1901. It then deals with the two very minor amendments to the Confession made within the Presbyterian Church of Australia since Union.
