It is like as if several tectonic plates around the Anglican world are shifting; and this shift is about to trigger a huge tsunami tidal wave in the great big sea of Anglicanism. This has been happening for quite a while now and is nothing new but I am just starting to listen in on this conversation (or rather, dispute) to learn about what is going on.
For those who do not know anything about what the Anglican Communion is about, it is like a big umbrella that holds all Anglicans around the world together, and this umbrella feels like it is about to split at the seams.
For traditional Anglicans, it seems that the Anglican provinces of Canada and the United States within this Communion are desiring to move away from its traditional Christian beliefs regarding same-sex marriage. For traditional Anglicans, they claim that it is not only about same-sex marriage but also about the way Christians should view scripture.
Many traditional Anglicans do not approve of this revisionist agenda because they feel that its leaders are trying to move the Anglican Church of Canada and the Episcopal Church into uncharted unorthodox waters. The “revisionist agenda” is a label pinned on the liberal movement to “unorthodoxy” (which can also be a loaded term to those on the liberal side of Anglicanism).
Note: A conservative site to peruse through is at the Anglican Network website of video on YouTube, and documents and PowerPoints from the natonal conference). It gives you a sense of what is happening from a traditionalist point of view.
