Undermining Christian mission is a constant threat, on the horizon, and already in the midst of churches, seminaries, and Christian organizations. Our call, our sacred duty and privilege, is to proclaim, explain, defend, and apply the truth of the one true and living God, and to endeavor to do this in every area of life and thought. As Francis Schaeffer so often affirmed, “The Lordship of Christ covers all of life and covers all of life equally.”
Seminaries can undermine their very reason for being—making known the truth of God. If so, they deserve a millstone around their necks, not a crown on their heads. One assured way of deconstructing the mission of God is to deny propositional truth and knowledge as belief aptly supported by reasoning and evidence.
Just today I listened to the concerns of a student at a seminary—not my own—who was told that the theories of George Lindbeck should be embraced. The truth-decaying, knowledge-undermining philosophy of postmodernism (or post-liberalism) is welcomed and dissent is not allowed. Truth Decay, my 2000 jeremiad and apologetic, takes this on, but let me reiterate.
Professor Lindbeck and his followers (such as the late Stanley Grenz) deny that the affirmations of Scripture are true in the sense of matching objective reality. Scripture gives us the rules for shaping the church. It cannot speak beyond that as to mind-independent states of affairs. This view is theologically deadly; it is funereal in tone, if popular among benighted advocates.
First, this view commits the fallacy of false dichotomy, which is, perhaps, the most commonly practiced fallacy today. Yes, the Bible tells us how to live for God: Love God and neighbor according to biblical revelation and godly character. Rules are required. But rules are only worth following if they work with the grain of the universe and cohere with the mind of God. Christ calls me to serve “the least of these” because as we do, we serve Christ himself. The rule is tied to the reality, the objective, Christological state of affairs.
Second, all sixty-six books of Holy Scripture affirm a propositional and correspondence account of truth. A proposition is what an indicative statement means. Statements can be read or affirmed in various languages because they share propositional content. I often have my students say aloud “Jesus is Lord” in as many languages as they can. Despite the differences in words and sounds, they mean the same thing (however slight the difference in nuance). A proposition stakes out the facts—either rightly or wrongly. Yahweh is the true God. Baal is not. Jesus is the way. Buddha is not. If a proposition corresponds to the reality it describes, then it is true. This is the metaphysics of truth, what truth is. Without this understanding, Christians can only talk to themselves—and not make much sense of it either.
Third, the mission of God is to reveal the truth of God so that it is known and obeyed (Matthew 28:18-20). For this, we need knowledge, not mere belief. A truth claim can only be knowledge in a person if that claim matches reality (Jesus is Lord) and if one has adequate justification for that claim (the claims and credentials of Christ).
I address all this is great detail in Truth Decay and Christian Apologetics. For now, I exhort all my readers to not be blown by every wind of doctrine, but to be firmly rooted in the truth of Scripture. Truth is nothing to play with; revelation is nothing to reject through shoddy thinking.
