Where's the P.o.a.b?
I dare you. Scour the whole Augsburg Confession to find the Priesthood of all believers. Regin Prenter, the great Danish theologian of whom few have heard, wrote in this article in honor of the great Leif Grane that it the CA should have stressed this aspect. Looking in the index to the Kolb/Wengert edition of the Confessions doesn't turn anything up either. Not that it isn't there or wasn't ever a part of the catholic tradition. Or that the Augsburg Confession itself says that not everything that it could have said needed to be said (see the conclusion to the CA).
