In a previous post, I mentioned a resolution of the Wyoming District that addressed the false distinction between unity of faith and concord of doctrine. It doesn’t work to divide them because faith must always have an object, and therefore a content. That content is the doctrine. Unity of faith and concord of doctrine are not different ways of looking at the same thing. They are different ways of saying the same thing; they are exact synonyms. Any attempt to put distance between the two terms is an attempt to destroy the confessional basis of “The One Holy Catholic and Apostolic Church”, which we usually shorten to “The Lutheran Church”.
I scanned the resolution which our district passed at that time. Perhaps it will help to elucidate what I wrote previously.
