by such change in circumstances that in the judgement of the superior they have become harmful; a personal privilege is extinguished by the death of the privileged person, real privileges cease by the total destruction of the thing or place, but the latter revive if the place be restored within fifty years; they cease also by the lapse of the time or the completion of the number of cases for which the privilege was given (Can. 72-77).
5. On the privileges of the clergy see the Code of Canon Law, Canon 118 ff.
6. Religious Orders have at different times received very ample privileges from the Holy See, so as to enable them to work for God and the Church with the greater freedom and fruit according to their Institute. These privileges are granted immediately to the religious superiors, and are by them communicated as occasion requires to their subjects. The regular or mendicant Orders, who take solemn vows, are exempt from the jurisdiction of the Ordinaries, and subjected immediately to the Holy See. Exemption, however, and many other privileges of religious have been largely curtailed, especially since the time of the Council of Trent, and now, as far as their work among the faithful is concerned, and their public conduct, regulars are to a great extent subject to the authority and correction of the Ordinary.
