"What, in your opinion, makes a person Catholic?"

CC theologian, R. Mc Brien,  put it this way: "To be Catholic -- whether Latin/Roman rite or non-Roman/Latin rite --is to be in full communion with the Bishop of Rome and as such an integral part of the Catholic Communion of Churches" [all 24-- 23 Eastern Catholic and Roman/Latin/Western Churches]."
Anglican theologian A. McGrath notes about the CoE: "..state and parliamentary documents regularly describe" the Church of England as "the Protestant Episcopal Church of England and Ireland." Its titular head, the queen, promises to uphold the "Protestant faith." (The Episcopal C. originally was the "Protestant Episcopal Church.") It's hard to know which voice speaks for Anglicanism owing to its ecumenical inconsistency (in doctrine/practice), especially regarding Lutherans, Protestants (whom -- through the Provoo Agreement -- they are in communion with), etc. What their ecumenical right hand does often contradicts what is done by the left.
