Or perhaps we're slightly more sophisticated than that and we appeal to tradition to adjudicate its meaning. In any discussion of how we understand Scripture, we must consider reformation principles. The Reformers' methodology was one born of conflict with Rome. Tradition has equal authority with Scripture. Without tradition, we are, at best, wandering in a forest at night with a candle.
Tradition is a guide, but a fallible one.
Tradition cannot stand on equal footing with Scripture. Scripture interprets itself. If there are two contradictory interpretations, the one in closest harmony with the unified teaching of Scripture is to be adopted. This is an organic, internal approach to handling Scripture. Luther points to Christ as being the consistent internal message of Scripture.
