Question Corner: How does someone become an exorcist today?

A local bishop appoints priests to the role of exorcist, according to the Catholic Review. There is no specific liturgical ritual or special ceremony used to confer this office today.

While the ministry of exorcism belongs to the diocesan bishop, he may assign the task to a priest. A prerequisite for serving as an exorcist is ordination to the priesthood. The most recent rite of exorcism notes that the office is committed to a priest either stably or for a specific period.
