This overview chapter for the fourth part of the book covers theologies of salvation from the eighteenth to the twenty-first centuries. It covers John Wesley, Friedrich Schleiermacher, Karl Barth, Hans Urs von Balthasar, Karl Rahner, and Gustavo Gutiérrez. In the overview chapter, Ryan Reeves explains that the unique context of this period of time provides an intriguing backdrop for competing theologies of salvation. The dawn and subsequent growth of modernity and the rise in rational, empirical thinking in this period reveal the need for theologians to re-examine both the nature and effects of salvation.
