As there are scarcely any but
persecuting religions that have an extraordinary zeal for being
established in other places (because a religion that can tolerate others
seldom thinks of its own propagation), it must therefore be a very good
civil law, when the state is already satisfied with the established
religion, not to suffer the establishment of another.
[19]
This is then a fundamental principle of the political laws in regard
to religion; that when the state is at liberty to receive or to reject a
new religion it ought to be rejected; when it is received it ought to be
tolerated.
