I have enjoyed William Barclay's work particularly on the letters of St. Paul over the years. I feel , however, that I must withhold my "excellent" rating in all categories other than the quality of the book's appearance.
Why it is that people feel they must change words that radiate the majesty and clarity of older biblical translations escapes me. The use of what appears to be an attempt to "dumb down" the language of even the NRSV I believe is to cater to the laziness of today's readers to learn read, think and contemplate in a far more noble use of English prose. I am of course referring to the biblical text prior to each of Barclay's commentary. This does not otherwise diminish the Spirit filled, Christ centered exegesis of William Barclay.
The whole Barclay commentary series is clearly written, in an understandable, popular style, but still deals with textual and historical issues necessary to gain a clear understanding of scripture. Where there are disagreements among scholars, Dr. Barclay expresses his understanding, but presents other interpretive positions clearly so the reader may, through prayer, study and the leadership of the Holy Spirit, gain greater insight into the (divinely inspired, inerrant, authoritative) Word of God.
This book was a wonderful book. It allowed me a very clear and easy way to better understand the book of Romans. I have enjoyed every one of William Barclay's books that I have read and have found they are excellent study guides.
