"The SS had been organized by Himmler according to the principles of the Jesuit Order. The rules of service and spiritual exercises prescribed by Ignatius de Loyola constituted a model which Himmler strove carefully to copy. Absolute obedience was the supreme rule; every order had to be executed without comment." Walter Schellenberg, Chief of the S.D., counter-espionage, and was close to Himmler.
Quoted by Edmund Paris, on page 253 in his 1964 book The Vatican Against Europe, cites "Le chef du contre-espionnage nazi parle" (Julliard, Paris 1957, pp. 23 and 24.)
