They are not only approved but posted, which is a new policy. The article used constitutions and statutes interchangeably, which someone might want to explain for LARC readers. Is that sloppy reporting or are we looking for a distinction that isn't there?
In the case of the Legion, the approval of the constitution fulfills one of the requested steps of the renewal process started under Benedict XVI in 2010, when he named Italian Cardinal Velasio De Paolis as Pontifical Delegate to lead a process of reform, which continued under Pope Francis.
The text is the result of a three-year period of consultation in which all the members of the Legion had the opportunity to participate and contribute.
The definition of the “charism,” which in management terms would be defined as the order’s mission, was also part of the renewal process and it can be found in the new Constitutions.
According to Article Four, Legionaries should “bring others to live out their baptismal calling to the full, fostering the spiritual growth, the integral formation and the apostolic outreach of the men and women.”
Of course, "integral formation" has been a trademarked term that was essential to the toxic methodology previous to this point -- and remains a nebulous term even now. But the Church has signed off on the group, leaving the laity to weigh the value in the future.
