The epistles present a heartfelt testimony from Robert Rich to seven distinct Christian denominations, emphasizing God's approval of righteousness across various beliefs while denouncing evil. Each letter addresses a specific church, reflecting Rich's insights into their practices. Additionally, the work includes an abstract of a letter detailing his benevolence towards these communities. This book is part of the Sabin Americana collection, which offers a rich historical perspective on life in the Americas from the late 15th century to the early 20th century.
