Well personally, I am going to say that I think it is a tragedy. It is a tragedy because the real message of Christ is just as relevant today as ever, if not more so. If churches like the Anglican church wither and die away, I think it is sad because I think the real reason will because a lot of people simply have not opened their minds to a new understanding of what Christianity can be. If Christianity has to go, it will go. But I'd like to see it go after it gets a fair shake. Currently, it is not getting a fair shake. Fundamentalism and theistic ways of interpreting Christianity are not the only way of viewing and experiencing Christianity. For most people, I don't think they have ever known this. Christianity dying away without people having the opportunity to experience a new, vibrant way of living into it, is quite a tragedy.
This is all my opinion of course.
