Kevin J. Vanhoozer is a theologian at Trinity Evangelical Divinity School.  He has a Ph.D. from Cambridge University.
Biblical Authority after Babel addresses a prominent 
criticism of the Protestant Reformation.  The criticism is that the 
Reformation led to interpretive anarchy regarding the interpretation of 
the Scriptures.
Roman Catholicism holds that the church founded by Jesus, which it 
understands to be the Roman Catholic church, has the 
divinely-commissioned authority to interpret the Scriptures.  When 
Martin Luther came forward and proclaimed that the Roman Catholic church
 was incorrect on justification, and thus wrong in its Scriptural 
interpretation, Luther was saying in effect that people can challenge 
the church if they believe that its teaching is contrary to the Bible.  
The problem is that the Bible can be interpreted in different ways.  The
 Reformers found this out when they disagreed among themselves about how
 and whether Christ was in the Eucharist!  If we reject the idea that 
the Roman Catholic church has the authority to interpret the Scriptures,
 does that mean that we are giving interpretative authority to each 
individual?  Critics claim that this had led to chaos!  Not only has 
Protestantism splintered into numerous denominations, but there are also
 Christians who act as if they are their own private pope, interpreting 
the Bible as they see fit.  Can the Bible even have authentic authority,
 if that is the case?
Vanhoozer argues that even the Protestant Reformers regarded the 
church as essential, meaning that they were not promoting individual 
Christians doing their own thing, acting according to what was right in 
their own eyes.  Vanhoozer notes that Martin Luther and John Calvin were
 not against catholicity with a small “c”: they were all for the church 
as a broader body making decisions.  But they were opposed to defining 
the church as Rome, denying that this approach was truly catholic 
(universal).  Vanhoozer highlights the importance of the church: the 
word of God brings into existence a church, and the priesthood of 
believers presumes a church community where believers can minister.  
Vanhoozer also maintains that the traditional creeds of the church and 
the traditional rule of faith can provide boundaries for Scriptural 
interpretation.
Vanhoozer’s practical advice is what one would expect in a book such 
as this.  Concentrate on the essentials of the Christian faith (i.e., 
the Trinity, Christ’s resurrection, the Gospel), learn from each other, 
and be charitable amidst differences over the less-essentials!  
Vanhoozer does well to define what is essential and why: without the 
essentials, the Gospel would be unintelligible.  Vanhoozer also talks 
about how denominations can work together.  Vanhoozer is sensitive, 
however, to the unhelpful directions in which such advice can be taken. 
 For instance, he does not favor an ecumenicism that focuses on the 
least common denominator of Christianity.
In the course of his book, Vanhoozer has various discussions.  He has
 chapters about the solas of Protestantism: grace alone, faith alone, 
Scripture alone, and Christ alone.  His discussion on grace refers to 
the theological debates about the extent to which human nature can 
respond positively to God, and the extent to which God’s supernatural 
grace is necessary for this to happen.  Vanhoozer somewhat sidesteps 
this debate by defining grace rather broadly, as he regards creation and
 redemption both as acts of grace (i.e., God sharing or communicating 
Godself).  In addressing the Protestant concept of Sola Scriptura, 
Vanhoozer denies that Sola Scriptura means Solo Scriptura.  Vanhoozer 
supports drawing from church tradition in theology, but he maintains 
that Scripture should be regarded as the final authority.  Vanhoozer 
shares the quote that “our final authority is Scripture alone, but not a
 Scripture that is alone.”
This book certainly is thoughtful and informative, which is to be 
expected from Vanhoozer.  Vanhoozer interacts with theological thought 
in a sophisticated manner.  For instance, in summarizing other scholars’
 criticisms of the Protestant Reformation, Vanhoozer not only discusses 
the main topic of the book, but related issues as well.  One criticism 
Vanhoozer mentions concerns whether Protestantism’s abandonment of 
allegorical interpretations of Scripture, in favor of 
grammatical-historical exegesis, coincides with a secularizing 
de-sanctification of creation.
Vanhoozer is rigorous in wrestling with the problem of interpretive 
anarchy, and one may say that Vanhoozer has already addressed the 
criticisms that I am about to advance.  I admire Vanhoozer’s effort, but
 I still question whether he successfully eliminates the problem of 
interpretive anarchy.  Vanhoozer largely appears to presume that mere 
Protestantism represents the correct interpretation of Scripture.  Many 
Catholics have argued, however, that the Protestant view of 
justification by grace through faith alone is at odds with aspects of 
Scripture, such as the Gospel of Matthew, the Epistle of James, and even
 parts of Paul’s writings.  Vanhoozer believes that the Nicene Creed is 
consistent with Scripture, but there are biblical scholars who hold that
 the New Testament contains a variety of Christologies.  Looking to 
Scripture as the final authority does not necessarily eliminate 
ambiguity, even over what Vanhoozer may consider the essentials.
I should note, however, an intriguing statement that Vanhoozer makes 
on page 101, in the Adobe Digital version: “While there are indeed a 
variety of interpretations, especially about how salvation happens, mere Protestant Christians agree about what happened and who
 did what (e.g., Father, Son, and Spirit).”  Vanhoozer here is 
specifically addressing Protestant divisions on such issues as baptism, 
but his insight may be relevant to the disagreement between Catholics 
and Protestants on justification.  Both can find areas of overlap on 
what happens in salvation and who does what, notwithstanding their 
significant differences.
Successful in terms of its mission or not, this is still a rich book.
I received a complimentary copy of this book from the publisher through Netgalley.  My review is honest!
