I suspect many Reformed people will find it difficult to sympathize with my claim that theological perfectionism is a problem. Most Reformed people would argue that lack of concern for theological precision is a much bigger problem facing the church today. And when one looks at the state of modern evangelicalism it is hard to disagree. There is too much error, not merely on the finer points of theology, but with regard to the very foundations. How many evangelicals can articulate the gospel clearly and accurately? But without denying the dangers of theological imprecision, I have come to believe that theological perfectionism is another problem we should be concerned about, especially we who are Reformed.
You should read the rest of the article. I highlighted the first paragraph because I think he nails his point there. There is immense need within the church for a deeper commitment to theology, but there is also a danger of swinging so far in the direction of valuing theology that we value it for its own sake. When we start to care more about being accurate than about knowing God and sharing His incredibly good news with those who need it, we've completely missed the boat.
