I just saw this link from the Gospel Coalition.
It says what I have been saying on the Board for a long time. Well worth a read.
How ‘No Creed But the Bible’ Subverts the Bible
He has a number of problems. First, he lists only "particular" creeds which shows his slant on things. The author is trying to push Calvanism and eject any belief that runs counter to that. He is unable to do that with the Bible, so he is using a creed to try to do it.
Second, there is a reason why many avoid creeds.
First, words get redefined, created, or simply divorced from their original meaning. Regenerate does not carry the same meaning to me and born-again or obtaining a new heart. My definition of grace doesn't agree with that of the New Hampshire or London confessions. I believe in predestination too, but my definition for the word is completely different. With the bible, I can see a clear context to the meaning of the words. With a creed, I have no context. The creed is basically meaningless. This is why many say we may use the same words, but we use different dictionaries.
Second, once you announce your creed, it is very hard to go back on that creed. The creed literally becomes an addendum of the Bible people will fight to defend fiercely for. One local church has the Rapture in the creed. (Another word not in the Bible.) Now they will as fiercely defend their belief in the Rapture as the death and resurrection of Jesus.
Third, formal statements of religious beliefs have denounced believer's baptism for a millennium. Should there be any other reason why Baptists should avoid creeds? These statements of religious belief have fought against and still fight against one of the cornerstones of what it means to be Baptist - believer's baptism. Lutherans, Presbyterians, Methodists, Anglicans, Catholics, Orthodox, etc. all support infant as oppose to believer's baptism. All of the founders of Baptist churches rejected the creeds of the churches of which they were originally members.
Only scripture was also the battle-cry of the founding Baptists. It's how Baptists got started.
