The word Protestant actually refers to anyone who is not of the Catholic religion. Baptists were never a part of that religion and formed separately, which is why it was so strongly persecuted by the Roman Catholic religion.
Jon-Marc, you are obviously confusing the Baptists with the Churches of Christ.

Church of Christ churches are a late schism off of the Baptist tree. Catholics had a schism with Baptists back around the time of Constantine.
there are no denominations in Gods kingdom catholic or Protestant. god does not know Catholic, baptist, methodist, Lutheran God knows no pet denomination or one the considers it is true or more rigth church than another. Names are only walls of division that house many differnt rligious ideals and doctines mostly of men
the church is the church and it is comprised of all who worship Christ in spirit and in truth.
It is true when you say Protestnts are those who are not of the Catholic religion. That the problem. Its just religion. this can be protestants also. Lets drop religion and the names doctrines and ideals that divid and confuse who the church is ad focus on who we are in Christ.
Amen, I second this post.
