I went to Episcopalian schools from kindergarten through high school. What is frightening is that the service we went to once a week is virtually the same, in many sections, as the NOM; I mean word-for-word! I am not even talking about High Anglican stuff here, folks!
If unquestionably Protestant worship is the same as (or shockingly similar to) the NOM, it does not take a master of philosophy, syllogisms, etc., to conclude: the NOM is Protestant.
