Incardination and excardination

In the Roman Catholic Church, incardination refers to the situation of a member of the clergy being placed under the jurisdiction of a particular bishop or other ecclesiastical superior. Its antonym, excardination, denotes that a member of the clergy has been freed from one jurisdiction and is transferred to another.

Both terms are derived from the Latin cardo (pivot, socket, or hinge), from which the word cardinal is also derived—hence the Latin verbs incardinare (to hang on a hinge or fix) and excardinare (to unhinge or set free).

The purpose of incardination is to ensure that no cleric, whether deacon or priest, is "freelance", without a clear ecclesiastical superior to whom he is responsible.

In the Church, a man is incardinated as the clerical subject of a diocesan bishop or his equivalent (a vicar apostolic, territorial abbot, territorial prelate, superior of a personal prelature, etc.) or of a religious institute, society of apostolic life or secular institute upon ordination to the diaconate: within the ordination ceremony prior to the actual sacrament of Holy Orders itself, the man places himself under a promise of obedience to his bishop or other ordinary of a particular church, or makes an acknowledgment of a pre-existing vow of obedience to a prior, abbot or other superior in an institute of consecrated life or society of apostolic life.
