they will not “compromise the integrity of its mission”
as a non-Catholic, I am unfamiliar with their institutional organization structure
were they organized/established by the Roman Catholic Church?
or did they “self organize” without an institutional mandate from the Church
If their group is a creation of the Church, then isn’t their “mission” something assigned to them BY THE CHURCH, and if that’s the case, then isn’t it NOT subject to the mere interpretation of the sisters?
As I said; as a non-Catholic, I am unfamiliar with the institutional relationships involved, and can only make assumptions, with that ignorance.
The way I understand it in practice it is a combination of both. A group of men or women Catholics would approach the Church and ask to organize a community. They can organize freely, but the Church does not need to recognize them. If they are to get official recognition, they do need to submit to the Church's authority. In order to get recognition, they do need to be an organized and functioning community, and allow the Church time to decide to grant recognition. The other way religious groups form is to break off another previously established order, for some reason such as establishing themselves in another region.
