text: "...but the Episcopal Church does not consider itself "protestant."
  
  But the Episcopal Church's legal title is still "the Protestant Episcopal Church in the United States of America." (Just as from a historical perspective, the Anglian Church in England or Church of England must still be regarded as a Protestant variant -- the "Protestant Episcopal Church of England and Ireland" as state and parliamentary documents regularly describe it [notes Anglian Theologian, Alister McGrath]). The Episcopal Church is about as protestant as one can get in the US and for that reason is always listed under mainline Protestant churches. Its legal title, of course -- more than anything else -- indicates formal support of and investment in the designation: the "Protestant Episcopal Church in the United States of America."
