In persona episcopi

In persona episcopi English: In the grownup of the bishop is a Latin expression used by the Roman Catholic Church to indicate a union of two or more dioceses in which the dioceses are administered by a single bishop but undergo no alteration to their diocesan frameworks e.g. seminaries, cathedrals, curia officials. In its mildest name such a union can be temporary, but in other cases it can be an intermediate step towards a union aeque principaliter or a full union.
