What source are you quoting, Preacher? Cause I disagree.
A Protestant denomination is a denomination that came out of the Catholic religion during the protestant era. Hence the name Protestant. Lutherans, Presbyterians, Anglicans, etc. Some would even include Methodists but they came out of the Anglican church later on I believe.
Baptist history is fascinating although I don't know it as well as I would like. But basically we never came out of the Catholic Church but go back through the "Anna-baptists". And the Anna baptist existed for centuries right along with the Catholic church.
It's splitting hairs and most people of today would lump us in with the Protestants but its a label that technically doesn't apply.
That is an excellent statement.
