The first members were Scouts and Guides of the Katholische Pfadfinderschaft Europas, the Austrian and German branch of the Union Internationale des Guides et Scouts d'Europe. Until today the pastoral care of the scout groups is the main priority of the congregation.
In 1994 the Servi Jesu et Mariae were recognized as a Congregation of Papal Law and was attached to the Pontifical Commission Ecclesia Dei. According to themselves they try to fulfill the preconciliar life of the Jesuits. In accordance with that goal they celebrate the Mass according to the Roman Missal of 1962, but also use the new, current missal of Pope Paul VI from 1969.
In the beginning the scholastics of the Congregation went to the seminary of the Priestly Fraternity of Saint Peter and to the seminary of the Diocese of Fulda, but now they have their own seminary in Blindenmarkt in Lower Austria, which is also attended by seminarists of the Institute of St. Philip Neri, another Ecclesia Dei group.
