Why is an unconditional subscription to the Lutheran Confessions so important?
Authentically Lutheran churches insist on a subscription to the Confessions because they agree with the Bible, not merely in so far as they agree with Scripture. Otherwise, there would no objective way to make sure that there is faithful teaching and preaching of God’s Word. Everything would depend on each pastor’s private opinions, subjective interpretations, and personal feelings, rather than on objective truth as set forth in the Lutheran Confessions.
