A person who believes in or belongs to congregationalism; a member of a Congregational church where each congregation is independent and self-governing.
From 'congregationalism' plus the suffix '-ist' (one who practices or believes in), used in English religious contexts since the 17th century.
If you're a congregationalist, you believe that your local church community should make its own decisions rather than taking orders from a central church authority—it's about grassroots religious democracy.
