I really hate this. Anglicanism properly understood does have coherent doctrine. It just so happens that the vast majority of practising Christians who call themselves Anglican choose to ignore that, and either become quasi Romanists, quasi Calvinists or outright liberals who reject a great deal of the faith altogether.
Anglicanism is misunderstood in the greatest part, because it attempted to restore Christianity to the teaching and practice of the early, conciliar Church. That has given way to innovation. Justification by Faith, that very clear Pauline doctrine, has been ignored or subverted. 1662 has been denigrated because it does not conform closely enough to the Roman mass.
In England at least, our loss of faith in true Anglicanism is partly a product of our decline in national self confidence. Our church, whose culture engendered one of the freest and most prosperous places on earth, has been reduced to rubble, so much so that British adherents of other religions, who in the past would not dare do this, can openly mock its parlous state. I just thank God that 1662 is still the legal standard of doctrine and practice for Religion in English law. Feel much like a remnant sometimes, especially when other Christian groups use these temporal problems as evidence that our religion is false.
Anglicanism, properly understood, is the faith of the Apostles. It’s a shame nobody understands any more.
