I'm with Bill on this one. Just what is a protestant?
I agree with both of you. However there are some churches, primarily "main line" denominations which refer to themselves by that term.
I believe you will find that the Presbyterians, Lutherans, Episcopal, Congregationalists and certainly the Anglicans among others, endorse this lineage.
They consider themselves as derived from the original "protestors" of the fifteenth and sixteenth centuries. Primary being Martin Luther,
John Huss,and some even hearkening back to Peterof Bruys (Pierre De Bruis) in the tenth century.

Many Baptists and independants deny this, pointing back to a heritage that cites a lineage for them outside the Roman Catholic tradition. I tend to agree with that..
In any case, THe pope seems to have provoked a division in the RC Church....he is bucking the traditional values...just as some of the "woke"
Protestant congregations are doing.
The upheval in the Vatican, is similar to the upheval within the Presbyterians, United Methodists, Lutherans, Southern Baptists and others in the recent past. Judging by Obama's Rev Wright, the UCC has gone haywire long ago..
It is apparently even more divisive in the RC Church, due to the special powers and privileges vested in the pope.
