What term describes radical dissenters from the Church of England who sought a completely separate church?

The term that accurately describes radical dissenters from the Church of England who sought a completely separate church is "Separatists." Separatists believed that the Church of England was beyond reform and therefore sought to establish their own independent congregations. This group included individuals who felt that true worship and a genuine relationship with God could only be achieved by breaking away from the established church and forming their own distinct communities.

While Puritans sought to reform the Church of England from within, Separatists took a more radical approach by advocating for a total separation. The Anglicans, on the other hand, were the adherents of the established Church of England, which further distinguishes their beliefs from those of Separatists. Loyalists referred to colonists during the American Revolution who remained loyal to the British Crown, and therefore do not relate to the context of dissent within the Church of England.
