Over the past 4 centuries, a multitude of commentaries have been written on the Anglican 39 Articles: Browne's is one of the few that may be considered a classic. Browne was a High Church bishop whose commentary avoids the extremes of Evangelical Anglican commentaries, Liberal commentaries, or Anglo-Catholic commentaries.
NOTE: This particular Kessinger Publishing edition is only Volume 2 of a two volume set and is therefore not Browne's complete work. Browne's work was originally published in two volumes and then later revised into one volume. There are other editions out there that reprint the single volume edition, which would be a more economical way to own Browne's commentary.
Several factors make Browne's commentary perhaps the best on the 39 Articles. One of the greatest aspects of Browne's work is its depth: in this edition the book runs to 860 pages. What makes Browne's commentary stand out especially are the two main sections into which his commentary on each Article is divided: History, and Scriptural Proof. In his History section, Browne surveys what Christian writers have said about the Article at hand from the early church until the 19th century. His presentation of patristic thought on each subject is particularly useful and illuminating. In his Scriptural Proof section, Browne thankfully discusses the passages in the Bible that bear on the Article at hand. Among the two sections, Browne offers his own view, which is almost always sound and judicious.
In presenting both the Historical and Biblical views of the Articles, Browne succeeds in his aim of proving the Articles to be both Catholic and Biblical. If I had to recommend only one commentary on the 39 Articles, this would be it!
