Peter Lopez has a very interesting discussion going on his blog at Beauty of the Bible on the relationship between the exercise of Charismatic Gifts and the study of Theology.
Christian devotes of both camps have a tendency to distrust the other sphere, which I think is a shame. God is One. Those who have hold of His right hand may perhaps be understood for thinking that others (holding His left hand) have everything backwards, but they are not excused for thinking so. God is God, truth is truth however God reveals it to us.
We discard any of it to our loss, and at our peril.
