It strikes me how often that is the case with Lutheranism. Not that we get things backwards, but that we affirm the inverse of what other's assert as truth. A few examples.
"The finite is not capable of the infinite." This was the definitive Calvinist answer to the Lutheran doctrine of the Eucharist (and of the means of grace and Christology in general). But what did the Lutherans say to this? "Ah, but the Infinite IS capable of the finite."
"Whatever is not commanded is forbidden." Again, a classic Reformed approach. But the Lutherans inverted it: "Whatever is not forbidden is permitted." Hence the Lutheran retention of so much of the liturgical treasure of the Church, her much more open approach to the Church of the Middle Ages and the ancient undivided Church.
"The Church preserves the Gospel." Thus the constant appeal to tradition in both Rome and the East. But what do Lutherans say to this? "Rather, it is the Gospel which preserves the Church!" And we point to tradition *as witness* to how the Gospel has done so!
"The Church interprets the Scriptures." Again a Roman and Eastern favorite, to which the Lutherans infuriatingly say: "Rather, the Scriptures interpret the Church." "A book can't do that!" is the claim. "This book can," our smiling response, "because this book is GOD speaking. His Word. Mighty and active. Just listen up!"
"We recognize the Sacraments are efficacious only when they are performed in the communion of the Church." Thus, guaranteeing the sacraments via the Church. We flip it: "We recognize the communion of the Church only because the Sacraments are efficacious." Thus, guaranteeing the Church via the sacraments.
Lutherans are so infuriatingly backwards to other Christian confessions and jurisdictions - but what freedom, what joy, yes what certainty in our delightful reversal of things! At bottom each reversal is founded in the belief and certainty that God's Word and promises can be banked on - without first getting the "a okay" from human reason or running any ecclesiastical safeguards into the promises of God.
