A consultor is one who gives council, i.e. a counselor.
In the Catholic Church, it is a specific title for various advisory positions:
- in the Roman Curia a consultor is an expert who advises the prefect, members, and staff of a dicastery on subjects relating to their expertise. These consultors can be members of the clergy, the religious, the laity, and possibly even non-Catholics.
- in a diocese, a college of consultors consists of priests charged with advising the bishop; one of the duties of the diocesan college of consultors is to elect a diocesan administrator during a period sede vacante.
- in certain regular congregations (i.e. religious orders) consultors can advise the superior-general, (e.g. the six geographically diverse consultors to the Superior general of the Passionists), provincial superior (e.g. Redemptorist Vice-provincials), or a local superior.
