Confessional protestant Christianity claims to hold to the beliefs of the ancient church including the Apostles, Nicean, Chalcedon and Athanasian creeds. They will say the bible is the "Primary Standard" for all they need to know about faith but claim these confessions and creeds are "Secondary standards" which are held to be the most faithful teaching of scripture. They also include their own confessions which were written after the reformation to more clearly enunciate the doctrines of the reformers (even though these doctrines are supposed to be self-evident and self-explanatory in the scripture.) One would wonder why they need any confessions at all if indeed the bible is perspicuous and the final arbiter to decide and teach all doctrines of their faith, but I digress.
When one looks at the ancient (pre-reformation) creeds they profess belief in the communion of saints, one baptism for the forgiveness of sins and the role of good works in determining where one spends eternity. None of these doctrines are held by post-reformation Christianity so how can they say they are confessional protestants? For instance, in the Athanasian creed we read: "At His coming all men will rise again with their bodies and shall give account for their own works. And they that have done good shall go into life everlasting; and they that have done evil into everlasting fire. This is the catholic faith, which except a man believe faithfully, he cannot be saved."
So somewhere, there remains a tremendous disconnect in what the confessional protestants profess and what they actually believe. I suspect they attempt to claim historic continuity with the ancients the way we Catholics do to validate their beliefs. The difference is we actually believe in and practice the doctrines of the ancient creeds and can historically document a 2000 year continuity with the apostles teachings. The confessional protestants saying that they believe in the creeds doesn't make it so. The beliefs of modern day confessional protestants bear no resemblance whatsoever to the beliefs proclaimed in the early church creeds, with just a few exceptions.
