 Pope Pius XI believed that the movement used Catholicism for its own political ends and placed the movement's newspaper on the Index Librorum Prohibitorum which meant that it was banned from all Catholic homes.Billot expressed strong disagreement with the decision, saying that the political activities of monarchist Catholics ought not to be censured by Rome.On 13 September 1927, in a meeting with Pope Pius XI, Billot submitted a letter asking to be allowed to resign as cardinal.
