Canon 921

1. Juridic persons are constituted for a purpose in keeping

with the Church's mission either by actual prescription of the

law or by a special concession of the competent authority granted

by decree. 2. By the law itself Churches sui iuris, provinces,

eparchies, exarchies as well as other institutes expressly established as such in common law are juridic persons. 3. The competent ecclesiastical authority is not to confer juridic personality except upon those aggregates of persons or things which

pursue a truly useful purpose and, all things considered, have

resources which are foreseen to be sufficient to achieve their

designated end.
