Well mostly I get this impression by what I see. All one has to do is open up a newspaper that has a religion section and you'll see what the latest crisis in the Episcopal Church is.
And the stories that show up in the press aren't the sum-total of any Church let alone the Episcopalians/Anglicans.
A couple weeks ago I read an interview with "Bishop" Gene Robinson talking about how he is so happy to be a June Bride(if that isn't garbage I don't know what is) and this man is a Bishop of the Episcopal Church.
What *I* would call it is the the personal feelings and words of one man. I don't know him. He isn't my bishop. I didn't vote for him. He is one man and he gets press coverage because sometimes he says things that are, let's say, surprising or out of the ordinary. He's not the only Bishop, but most of the others aren't as controversial or perhaps flamboyant. However, he is still a human being.
Then you have diocese's splitting off and court cases regarding who owns Church property
Yes, I know about that. It's not limited to the Episcopalians either.
meanwhile at Christmas last year the ArchBishop of Cantebury said that the 3 wise men story may just be myth.
Did you read the interview in which that was said? I have and here is a link:
http://www.telegraph.co.uk/news/uknews/1573214/Archbishop%27s-interview-with-Simon-Mayo.htmlReading things *in context* can be very helpful.

The Archbishop is talking about what is actually in the Gospels and then how things have become attached to that. Here is what Cantuar+ said:
"Well Matthew's gospel doesn't tell us that there were three of them, doesn't tell us they were kings, doesn't tell us where they came from, it says they're astrologers, wise men, priests from somewhere outside the Roman Empire. That's all we're really told so, yes, 'the three kings with the one from Africa' - that's legend; it works quite well as legend."
It's not that the Nativity is a "myth" (like some of the headlines said) or that he doesn't believe in Jesus as the Son and born of a virgin (he does). It's the added on bits that aren't crucial.
We have an Episcopal Church in my town and their Rector writes in the religion section about all sorts of kooky left wing things. Two weeks back he wrote a column questioning the existance of not only Hell but God also. 
Is the paper on-line so that the column could be read please? I know that a lot of Montana papers have at least some of the publication on a website. Again, the context of the question or statement can be very important. What do you mean by "kooky left wing things" please?
If that's not enough two words:
Spong
Jefferts-Schori
I am not saying this to sound rude but out of sadness. I have been to a few episcopal churches and once one can get past the strange stuff they have a very beautiful liturgy.
Well, Spong is now retired and doesn't get nearly the press coverage he used to get that I'm aware of. Can you please be more specific about the Presiding Bishop please, before I write on that point?
Thanks
