The Oxford English Dictionary elaborates that an omnist believes "in a single transcendent purpose or cause uniting all things or people".
The Oxford dictionary defines an omnist as "a person who believes in all faiths or creeds; a person who believes in a single transcendent purpose or cause uniting all things or people, or the members of a particular group of people".
