The ecumenical movement of the 20th century was a quest for unity born of a missionary concern for the world. Thus, from the beginning of present-day ecumenism, mission has been inextricably linked with unity. This volume explores the themes of unity, mission, and their relationship. Seventeen Roman Catholic and Protestant scholars offer essays in honour of George Vandervelde, a leading evangelical ecumenist from the Reformed tradition.

with a Postcript coauthored by Michael W. Goheen

In print for two decades and translated into eight languages, Albert Wolters's classic formulation of an integrated Christian worldview has been revised and expanded to reach new readers beyond the generation that has already benefited from this clear, concise proposal for transcending the false dichotomy between sacred and secular. Wolters begins by defining the nature and scope of a worldview, distinguishing it from philosophy and theology. He then outlines a Reformed analysis of the three basic categories in human history -- creation, fall, and redemption -- arguing that while the fall reaches into every corner of the world, Christians are called to participate in Christ's redemption of all creation. This Twentieth Anniversary edition features a new concluding chapter, coauthored with Michael Goheen, that helpfully places the discussion of worldview in a broader narrative and missional context.

Praise for the first edition"This is the best statement I have come across of the 'reformational' Christian worldview. It is lucidly written, includes a lot of helpful analogies and illustrations, and is throughout generous in its spirit."
-- Nicholas Wolterstorff, Yale University"Translates the central insights and categories of the neo-Calvinist tradition into fresh, nontechnical language and clarifies them with a generous sprinkling of apt illustrations and images. . . . Highly recommended to all those desiring a crisp introduction to a Christian worldview in general or the neo-Calvinist tradition in particular."
-- "Christian Scholar's Review"Outstanding. . . . Deserves a wide readership not only in a specifically academiccontext among teachers, preachers, and students, but also among the larger group of believers who are concerned with issues involving Christian worldview, theology, and philosophy."
