A church named by a diocesan bishop to serve as a cathedral but which remains under the governance of the vestry and dean. It is used as a cathedral for diocesan purposes, but without the formation of a legal cathedral organization and without a cathedral chapter. It is not the official cathedral of the diocese. The church's status as pro-cathedral ends when the bishop no longer holds the diocesan jurisdiction, and the pro-cathedral's status may or may not be extended by the next bishop.
