"We may impress one another for a while by dropping the name of the latest book we've read, but secondhand food will not sustain and deepen our people's faith and holiness. Weakness in Greek and Hebrew also gives rise to exegetical imprecision and carelessness. And exegetical imprecision is the mother of liberal theology. Where pastors can no longer articulate and defend doctrine by a reasonable and careful appeal to the original meaning of Biblical texts, they will tend to become close-minded traditionalists who clutch their inherited ideas, or open-ended pluralists who don't put much stock in doctrinal formulations. In both cases the succeeding generations will be theologically impoverished and susceptible to error."
