“”It is sufficient” not only specifies the demands which Lutherans must make on others, it also limits the demands which Lutherans can allow to be made on themselves. Most bluntly stated: if other parties can affirm the gospel is preached acceptably among us, and the sacraments celebrated acceptably, they have no right to demand further uniformities as conditions of communion. Indeed, Lutherans have generally regarded any tendency by another party to make further demands for uniformity as prima facie evidence that the gospel is not being preached rightly in that quarter.”
- Lutheranism, 177
