Here are some sobering thoughts from John Frame regarding the task of theology for Theologians from "The Doctrine of the Knowledge of God":
And the qualifications for the ministry of teaching (theology) in Scripture are predominantly moral qualifications (1 Tim. 3:1ff.; 1 Peters 5:1ff.). Thus the quality of theological work is dependent not only on propositional knowledge or on skills in logic , history, linguistics, and so forth (which, of course believers and unbelievers share to a large extent); it is also dependent on the theologians character. (pp.322-323)
And regarding theological argumentation:
(1) First, the practice of taking an opponent's view in the worst possible sense, without first seeking to find a way of interpreting him so that his view is more plausible or even correct. Generally, this practice arises out of sheer hostility, blinding the theologian to more loving (and at the same time, more intellectually cogent) possibilities. This often leads to a "straw man" argument (ie., an argument against a view that the opponent does not actually hold, which perhaps, no one actually holds). (p.324)
Wise words from Professor Frame.
