In 1930, Rutherford was still holding to the 1874 Parousia.
Whether Rutherford's actions represents Christian spirituality depends on the meaning an individual understands by that term. And do not ignore Judaism in all of this, as the first-century followers of Jesus were Jews, the writers of the NT were Jews, Jesus was a Jew. They were all part of Second Temple Judaism. So what is Jewish Spirituality?
