The secretaries are appointed by the pope himself. They must be bishops, with the title of a church _in partibus infidelium_, or, at least, prelates of the Roman court. In the Congregation of the Holy Office the secretary is a cardinal.
The secretary has under him a number of inferior officials--a vice-secretary, who supplies his place when vacant; a protocol, who takes care of those records in which are registered current matters of business, with the state of their examination; a master of rolls, who preserves the various documents; and copyists, who prepare duplicates and exemplifications. All these are under his control, and for them all he is responsible. They are chosen at a general session and hold office for life. They rank in the order of their seniority. Their remuneration is moderate, but they enjoy it during life, even when sickness or old age prevents the fulfilment of their duties.
To these congregations, moreover, are attached a number of theologians and canonists, who act as counsellors in the investigation of different questions, and assist with their advice those cardinals whose place it is to determine causes. These also are appointed for life by the pope, and, as they are generally taken from the religious orders, they are never absent or obliged to leave Rome without the permission of the congregation.
These counsellors prefer their opinions in various forms, according to the character of the congregation. Sometimes one of them is requested to present a written solution of some especial question; sometimes they are all summoned to hold a united deliberation and give their collective vote before the cardinals.
The parties who appear before these congregations are represented in their presence by proctors and advocates. The proctors act in the same capacity as our attorneys. They are the true defenders of their cause by law and in fact. They compose the petitions, digest the informations, and direct the whole proceedings. Their profession is very honorable, but not open to every one.
Advocates are employed only in matters of higher importance, and seldom except in those of abstract law. They disengage, as far as possible, every question from the circumstances of fact which surround it, and examine it doctrinally from the most elevated point of view. Their profession is free; but in order to exercise it one must be a doctor of civil and canon law, and consequently must have spent four years in study at the Sapienza, or three years at the Apollinaria. They are not limited in number, and are permitted to appear before any of the congregations. There are also special advocates belonging to the consistory, who deal only with the process of canonization. All of these are men well versed in theological learning, canons, councils, ecclesiastical history, civil and canon law, and by their own erudition contribute vastly to the advancement of jurisprudence.
