Today's modern Anglican makes statements like this when describing the foundations of Anglican orthodoxy:
"There is nothing in being an Anglican that says we must agree on our approach to scripture. The only doctrinal documents agreed upon in the Anglican Communion are the Apostolic Creed, the Nicene Creed of AD 381 and the Chicago-Lambeth Quadrilateral. Each of the 44 member churches in the Anglican Communion are, however, free to adopt and authorize their own official documents, and the Articles are not officially normative in all Anglican Churches."
The statement is technically correct, but let's address three problems:
1. At one time the 39 Articles and a third creed (Athanasian) were normative, and the Chicago-Lambeth Quadrilateral was not. The Articles and the Athanasian Creed were spurned for a particular reason... because modern "Anglicans" preferred not to have such strong statements of Trinitarian and Reformed doctrine. If one wants to rediscover Anglican-ism, then returning to its original documents is the logical first step.
2. The Chicago Lambeth Quadrilateral was never normative throughout the Anglican Communion, and in the USA where it was officially adopted in 1886, the Anglo-Catholics (who predominate among Anglicans who call themselves 'conservative') don't follow it because it calls for only two sacraments. In a deeper sense, the C-L Quadrilateral should be criticized not for what it contains but for what it does not contain. It is a useless document for the purpose of discipline because it says so little about the nature of God, salvation, and truth. In fact, its purpose at the time was precisely the opposite of being an instrument of discipline... they wanted to water down the essentials of the Christian faith such that "all may be one", as it states. This is simply pathetic.
3. The Nicene Creed contains nearly 100% of what is necessary for a Christian to believe. Without too much effort, one can discover in its text the principles of the reformation's "Solas", and of "TULIP" (acronym that reformed Christians use to explain Christian salvation). But modern renderings of the Nicene Creed remove all of this doctrinal meaning.** So it is not true that the Nicene Creed is normative for Anglicans because in common usage one finds incompatible versions. Many of today's problems in the Anglican Communion began when its Book of Common Prayer was 'modernized' (1979 in the USA for example).
