Perhaps I should entertain the notion:
Rank Item Percent
1: Eastern Orthodox (100%)
2: Anglican/Episcopal/Church of England (98%)
3: Roman Catholic (92%)
4: Presbyterian/Reformed (91%)
5: Congregational/United Church of Christ (69%)
6: Lutheran (69%)
7: Baptist (Reformed/Particular/Calvinistic) (51%)
8: Church of Christ/Campbellite (27%)
9: Seventh-Day Adventist (24%)
10: Methodist/Wesleyan/Nazarene (20%)
11: Baptist (non-Calvinistic)/Plymouth Brethren/Fundamentalist (8%)
12: Anabaptist (Mennonite/Quaker etc.) (4%)
13: Pentecostal/Charismatic/Assemblies of God (4%)
One note: I happen to be studying both the development of the liturgy and the creeds, much of which material comes from the East. Perhaps I'm absorbing that.
Of course, getting 98% on my own denomination is reassuring. Though I do have to note that I agree with the author that he needs to further touch up the survey. In several cases I could frame variations that I think are currently held that might further distinguish his material and some that did not quite fit my understanding.
In Christ,
