On 10th August, 1906, Pope St. Pius X issued his Encyclical Letter Gravissimo Officii Munere on the French Associations of Worship:
10. Assuredly they will tax their ingenuity to throw upon Us the blame for this conflict and for the evils resulting therefrom. But whoever loyally examines the facts of which We have spoken in the Encyclical "Vehementer Nos" will be able to see whether We have deserved the least reproach-We, who, after having patiently borne with injustice upon injustice in Our love for the beloved French nation, finally find Ourselves summoned to go beyond the last holy limits of Our Apostolic duty, and We declare that We will not go beyond them -- or rather whether the fault does not lie entirely with those who in hate of the Apostolic name have gone to such extremities.
11. Therefore, if they desire to show Us their submission and their devotion, let the Catholic men of France struggle for the Church in accordance with the directions We have already given them, that is to say, with perseverance and energy, and yet without acting in a seditious and violent manner. It is not by violence, but by firmness, that, fortifying themselves in their good right as within a citadel, they will succeed in breaking the obstinacy of their enemies; let them well understand, as We have said and as we repeat that their efforts will be useless unless they unite in a perfect understanding for the defense of religion.
