Which creed? I would question how authoritative and dogmatic the creeds were to Anglicans, especially American Anglicans, when they were willing to drop one entirely from the Episcopal Church's Article 8 ratified in 1801. And yet this also leads me to believe they considered the Articles themselves as guides rather than sources of doctrine, since they changed the established Articles as received from the C of E in a number of ways to suit the needs of the new nation. They would not have done this unless they saw it merely as a church discipline, as opposed to doctrine. Consider the rule set out in the Ratification of the 1789 BCP for the PECUSA: "IT is a most invaluable part of that blessed liberty wherewith Christ hath made us free, that in his worship, different forms and usages may without offence be allowed, provided the substance of the Faith be kept entire; and that, in every Church, what cannot be clearly determined to belong to Doctrine must be referred to Discipline: and therefore, by common consent and authority, may be altered, abridged, enlarged, amended, or otherwise disposed of, as may seem most convenient for the edification of the people, "according to the various exigencies of times and occasions.""
