This section details the foundational ideas and statutes of the missionary association envisioned by Charles de Foucauld as a central project of his life. Initially drafted in 1909 and later streamlined in 1913 and 1916, the association is built upon two core principles. The first principle stresses that Christians, particularly the French, have long neglected their primary duty to evangelize non-believers, especially Muslim subjects living under French colonial rule. The second principle emphasizes that this difficult task requires more than occasional financial donations and simple prayers, demanding instead a sustained, active missionary spirit cultivated through a genuinely devout Christian life and adherence to an organized rule of discipline.
Charles de Foucauld intended for this framework to inspire every colonial power to establish similar unions dedicated to bringing the true religion to the indigenous populations dependent upon them. Over the years, the initiative gained official approvals from key religious authorities, including Bishop Bonnet of Viviers, Bishop Livinhac of the White Fathers, and Cardinal Amette. Presented as the unique legacy and final counsel of Charles de Foucauld to his friends, the association aims to support both clergy and the faithful by channeling their collective devotion toward comprehensive apostolic action.
