As a specialist in British political history of the first half of the 20th century, Richard Griffiths is highly likely to be better informed on this subject than anyone else in this thread. It should be noted that during his visit to Nazi Germany, before his meeting with Adolf Hitler, David Lloyd George had suggested to German Ambassador Joachim Von Ribbentrop that "if you could get Winston into your new church, it would be worthwhile."It has not been shut down because there is the potential for a good discussion, but this is a research forum that requires substantive sources. You have not provided much, even that book you have provided, have you read some of the peer reviews? Some of the sources are 2nd and 3rd hand.
His use of the word "church" was not in reference to that of Catholicism or Protestantism.
