Revision or evasion of doctrinal standards has been a destructive influence in church life over the last one hundred years or so. W.G.T. Shedd witnessed such a trend in the Northern Presbyterian Church of his own day with regard to The Westminster Confession of Faith. This book expresses the reason for his opposition to that trend. Calvinism: Pure and Mixed is virtually a defense of the reformed faith against many of the most common criticisms leveled against it.
The aim of the author is twofold: first, to explain some of the more difficult points in Calvinism, and thereby promote the reaffirmation of the Westminster Standards pure and simple, precisely as they were adopted by both schools in the reunion of 1870, instead of the revision of them as now proposed, which had it been urged at that time would have been fatal to the cause of reunion: and secondly, to justify and defend before the human understanding, that intellectual and powerful system of theology which had its origin in the biblical studies and personal experience of the two most comprehensive and scientific theologians of Christendom, Aurelius Augustine and John Calvin.
