The Sodalitium Christianae Vitae is governed by its Constitutions, which have been approved by the Holy See. These Constitutions establish the fundamental structure of the Society. They are called “Structures of Service” because in fulfilling each of the different responsibilities one looks to follow “the example of the Lord Jesus, who manifested himself to us as one who serves, and of Holy Mary, the Handmaid of the Lord”.

These structures are similar to those of the other Societies of Apostolic Life or Institutes of Consecrated Life approved by the Holy See.
