Not too long ago, in an effort to get a better grasp of the Lutheran doctrine of the Lord’s Supper, I was reading the chapters on the sacraments in Francis Pieper’s Christian Dogmatics, and I ran across this statement: “The difference between the Lutheran Church and the Reformed in the doctrine of Baptism is fully and adequately defined by saying that the former believes God’s Word regarding Baptism, the latter not” (vol. 3, p. 269).
Mathison then notes how often he's seen this argument, not only from Lutherans... but just about every group on a variety of Biblical issues. The author concludes:
The problem with Pieper’s statement is that he does not allow for any conceptual distinction between the infallible and inerrant Word of God and his own fallible and potentially errant interpretation of that Word. Thus, to disagree with his interpretation is to disagree with God. But this is obviously false. Presbyterians and Baptists do not reject the Lutheran doctrine of baptism because they disbelieve God’s Word. They reject it because they think Lutherans have misinterpreted God’s Word.
The fact of the matter is that people who believe equally in the authority and inerrancy of Scripture sometimes disagree in their interpretation of some parts of that Scripture. We know God’s Word is not wrong, but we might be. God is infallible; we are not. We are not free from sin and ignorance yet. We still see through a glass darkly. In hermeneutical and theological disputes, we need to make an exegetical case, and we need to examine the case of those who disagree with us. It proves nothing to make the bare assertion: “We believe the Bible and you don’t.”
Food for thought.
