Hmmm.......As an RE (reformed episcopalian), I honestly think the term 'anglican' is a bit to broad today. So much is put under that banner. The problem is the same as all other denominational labels.......unity. I know several pastors, fathers, and bishops under the 'anglican' banner that are quite evangelical.
The notion of a 'half-roman' is not without some merit. The worship is generally liturgical; ecclesiology obviously episcopal; and some traditions are certainly similar. However, I find the theology more reformational; just not radically protestant. Via media.
Ecumenism is an issue. Anglicans tend to view Rome as fallen brothers rather than all out lost. I also think many anglicans would be amryldians as well.
The problems have been around for a good time. The REC was formed in the 1800's due to some of these problems. Several ECUSA parishes have left for more conservative alliances.
Please realise that I am not an expert on these matters.
