101 Against such suspicions We solemnly declare with Apostolic sincerity that - without prejudice to the declarations regarding the power of Christ and of His Church made by Our predecessor, Pius XI, of venerable memory, in his Encyclical Quas Primas of December 11, 1925 - any such aims are entirely alien to that same Church, which spreads it maternal arms towards this world not to dominate but to serve. She does not claim to take the place of other legitimate authorities in their proper spheres, but offers them her help after the example and in the spirit of her Divine Founder Who "went about doing good" ( Acts x. 38).
