5. The Publication of Calvin's Institutes (1536)

First published in Latin, this very influential Systematic Theology of the Protestant Reformation had a profound effect on the development of Western Christianity, and the Reformed tradition in particular.

The work is organized in four "books" as follows:
BOOK FIRST - OF THE KNOWLEDGE OF GOD THE CREATOR.
BOOK SECOND - OF THE KNOWLEDGE OF GOD THE REDEEMER, IN CHRIST, AS FIRST MANIFESTED TO THE FATHERS UNDER THE LAW, AND THEREAFTER TO US UNDER THE GOSPEL
BOOK THIRD - THE MODE OF OBTAINING THE GRACE OF CHRIST, THE BENEFITS IT CONFERS, AND THE EFFECTS RESULTING FROM IT.
BOOK FOURTH - OF THE EXTERNAL MEANS OR HELPS BY WHICH GOD ALLURES US INTO FELLOWSHIP WITH CHRIST, AND KEEPS US IN IT.
