Of True Religion
 Of True Religion Heresy Schism Toleration; and what best means may be used against the Growth of Popery is the title of a polemical tract against the popery of the Roman Catholic Church published by John Milton in 1673. The tract addresses Milton's own problems with the doctrines practices and ceremonies associated with the pope or the papal system of the Roman Catholic Church and with what Milton called the implicit faith of its members.
