Okay, but it is being taught to seminarians...It isn't doctrine in the church. Last I checked, the Nicene Creed still stands. As long as that stands, no matter what seminarians are being taught, the resurrection will stand as a doctrine of the church. But....I think that "Resurrection being taught as myth" is just oversimplification and sensationalizing of what is actually going on. Other and different understandings of resurrection are taught, but "myth" in the sense of a nonsensical and untrue story, no seminary worth it's reputation would teach this. Many seminaries DO teach the resurrection stories as myths in the sense of stories that point to deeper truths and spiritual realities.
Unfortunately for some (fortunately for others), the mainline seminary has embraced a scientific and modern worldview and calls into question and brings into dialogue beliefs traditionally held. They are examined, re-examined, discussed, debated, re-thought, re-formulated, etc. This all part of the scholarly/academic process. This is what happens in education. And, Western Christianity has cerebral-ized its faith, it has turned theology into an intellectual rather than spiritual pursuit. It has turned it into talk about God by those who study religious philosophy, rather than God-talk by those who have experienced God. So, what do you expect?
I was, in fact, thinking of myth in the second sense, not as something that is "not true". THough both definitions are saying something is not true as historical narrative, and perhaps in other ways as well, so I don't think you can argue the richer sense of the word myth is no different, really, than the orthodox teaching.
Your two definitions of myth here do have a connection in this case, because Anglicanism doesn't teach that either of them are correct with regard to the Resurrection or Incarnation. We teach that those were historical events that happened in a particular time and place.
These are the most fundamental teachings of our faith, and they aren't without consequence. They speak directly to the way we that understand reality is structured - that is why the belief that they are historical facts is so important.
There has never been any authority given to change that in Anglicanism, and such authority would have to come from the Anglican Communnion as a whole.
Yes, it is being taught in seminaries, and that should be very worrying to you. Academics talking about different ways of thinking about our religion is quite different than seminarians being taught things those ideas are what we believe. There has always been all kinds of ideas that go on in academia, but academia helps inform our decisions, it does not make them.
I do not see how anyone can think it is acceptable for academics (who quite frankly have been a poor lot overall in the Anglican world in the last few years) get to define how we understand our most fundamental beliefs. What kind of individual or school decides it would suddenly like to teach its seminarians some new, unauthorized idea, as Anglican belief?
And speaking of heresy - if there are any changes in teaching that could be described as heretical, it is incorrect teaching about the nature of Christ, the Incarnation, and the Trinity. These are the subjects that all the major heresies are related to. And the teaching of the Resurrection and the Incarnation as a myth is far outside even the traditional Christological heresies. It would be closer to orthodox belief to be an Arian.
I agree that Western Christianity has tended to cerebralize its faith to a degree (though actually I am not sure that is the dominant trend in Anglicanism), but I'd only call it modern in the strict sense, as in, 19th century. Theology and even philosophy and science have actually moved on from there, but that is where a lot of Anglican "radical" thinkers are stuck. It is that approach which sees myth and what you might call historical truth as very seperate, and which takes a very linear approach to theology.
But I don't really think I can be blase that this has became acceptable to teach as representing Anglican belief.
