These are all great historic, orthodox creeds of the Christian Church. Included are good reformed statements of faith and some more modern councils on important issues. Obviously, some of these will not contain identical material (such as views on baptism) and I personally might not agree with all the content (like Christ descending into hell) but in general, these are good to stand by.
