Creeds: Public or Private

I do want to make the point here that Christians are not divided between those who have creeds and confessions and those who do not; rather, they are divided between those who have public creeds and confessions that are written down and exist as public documents, subject to public scrutiny, evaluation, and critique, and those who have private creeds and confessions that are often improvised, unwritten, and thus not open to public scrutiny, not susceptible to evaluation and, crucially and ironically, not, therefore, subject to testing by Scripture to see whether they are true.
