The final review for this course involves the book, System of Bible Doctrine, by John Thornbury. As a Baptist minister of fifty four years, Reverend Thornbury seeks to communicate what seems to be a very complex system of doctrine into layman’s terms, as stated in the rear cover’s summary:
“For too long it has been thought that the study of doctrine should only be undertaken by trained theologians and professional academics. Many believers are intimidated by complicated and obscure terms and are put off by concepts that bear the names of scholars who have been long dead. Teaching has been considered outdated and irrelevant.
John Thornbury aims to put such an idea to rest, as he sets out the main doctrines of the Christian faith, yet in a short and concise way. He does not attempt to explain truths in great detail with complicated theories, but allows God’s Word to speak for itself, plainly and simply, covering such things as what the Bible says about God and creation, man, the gospel, the Christian life, and the future.”
In fact, along with the subjects mentioned above, Thornbury deals with the subjects of grace, the Bible, and the church.
Well written, and indeed, concisely stated, the work does meet expectations in that the topics are not covered in great detail, complicated theological theoretical thought is not present, and concepts named after church fathers are not mentioned (with apologies to Calvin and Arminius). Yet for all its promise, the book does suffer from two major failings.
First, it fails in its implied promise to abstain from the use of “complicated and obscure” theological terminology. While the use of such vocabulary is severely limited, terms such as predestination, free moral agency, dispensation, imputation, infusion, propitiation, justification, and sanctification make their way into the discussion with little to no explanation. In short, the book, at times, seems to say, “you can take the boy out of seminary, but you can’t take seminary out of the boy.”
Second, and I feel more serious, is the clear theological bias present throughout the book. Thornbury makes it clear from the outset that he is writing from a conservative, orthodox, Calvinist, Baptist perspective. He also adds several theological “judgment calls”, as it were, all using variations of “it is my opinion”. To compound issues, Reverend Thornbury makes some dismissive comments regarding issues that he believes central to “liberal” churches; issues that are shared by churches that may in fact be conservative or moderate in theology. By choosing to abrogate a position of neutrality in his writing, Thornbury comes across not as a seasoned minister / theologian, but rather as someone with some axes to grind, and System of Bible Doctrine is his chosen grindstone.
In summary, System of Bible Doctrine fails to live up to its billing. While useful to those who share the author’s doctrinal positions, it is ineffective as a neutral, concise, and informative tome for doctrinal education.
