A personal prelature is a jurisdictional entity within the Church’s hierarchical structure, presided over by a prelate, answerable to the sacred Congregation of Bishops, and to which laity and clergy can belong. It is established by the Holy See for specific pastoral or organizational purposes, and it is governed by statutes given it by the Holy See. The word
personal indicates that it is defined by persons, whereas, for example, dioceses and parishes are defined by geographical areas (
