The Apostolat Militaire International is a global Catholic lay organization that unites military personnel to promote a Christian vision of military life, foster peace and cooperation, and address the moral and spiritual challenges of service in light of Church teachings. AMI comprises military associations from across four continents, governed by a General Assembly that includes an Executive Committee, 18 full-member delegates, two open memberships, and 19 associated friends. Recognized as an NGO, AMI promotes a Christian vision of military life, encourages international cooperation and peace, and addresses spiritual, moral, and social issues specific to the military in light of the Gospel and Church teachings.

Our history

Founded in 1965 in Santiago de Compostela, Spain, by Catholic military personnel from ten countries, AMI emerged from a shared desire to promote and live out the ideals of Catholic military service within the armed forces and public life. Its mission is to support those dedicated to serving their nations with integrity and a commitment to fostering true peace. AMI is officially recognized by the Holy See through the Dicastery for Laity, Family and Life as an association of the faithful and is a member of the Forum of Catholic-Inspired NGOs.

Our Goal

Guided by its Vision Paper 2021, AMI seeks to reach individual soldiers through multilingual digital platforms and a forthcoming mobile app while closely collaborating with Catholic military associations and Ordinariates. Additionally, AMI offers expertise to the Vatican and Catholic NGOs on just war, military ethics, and social doctrine and is actively involved in global events such as the International Military Pilgrimage at Lourdes and World Youth Day.

As a private association of the faithful with a juridical personality under canon law, AMI acts in accordance with the Second Vatican Council's decree on the lay apostolate, adapting its mission to the specific conditions of each represented nation.
