"As I have stated before
they have been wrong in their national affairs,
they have been wrong in political affairs,
they have been wrong in their religion and
they have been wrong in everything."
From the same page as the quote at the top:
the world has been apostate for generations past: it has been under the dominion of the prince and power

before they have been wrong in their national affairs, they have been wrong in political affairs, they have been
wrong in their religion and they have been wrong in everything.( JOD 6:167)
