Baptists break from Catholics and Protestants on the matter of innovation. Main line Protestants do not deny the church's ability to innovate, they simply disagree with some of the innovations of Catholicism and deny that church's authority. Baptists believe that most innovation is unnecessary and erroneous.
The average Baptist thinks that Lutherans, "High Church" Episcopalians, and Catholics 'dress funny'.
“Main line Protestants do not deny the church’s ability to innovate, they simply disagree with some of the innovations of Catholicism and deny that church’s authority.”
Actually, any denomination that holds to Sola Scriptura says that scripture - the Word of God - is authoritative in belief, and that nothing binding can be added or changed.
Good reading on the subject here:
