The authority in the Church rests in apostolic commission (succession), in the office of a bishop. Neither Protestants nor Baptists do not have valid clergy.
Chapter 15. Bishops and Deacons; Christian Reproof. Appoint, therefore, for yourselves, bishops and deacons worthy of the Lord, men meek, and not lovers of money, and truthful and proved; for they also render to you the service of prophets and teachers.
Appoint for yourselves? Who said that? No way to know & the The Didache didn’t make it into the canon. Is it any wonder why?
