The extension of the faith, the multiplicity of appeals to the holy see, the more complicated developments of modern life, and the increased entanglements of the church with the world have, however, rendered necessary a more frequent intervention of authority, and added vastly to the number of those causes on which the holy see has been obliged to pronounce judgment. The government of the church is by far the most extensive of the governments of the earth. It is not bounded by the limits of any particular kingdom, but reaches throughout the globe, as well to those countries whose heathen populations demand its constant care, as to those Catholic states which are directly subject to the jurisdiction of the apostolic see. From all these places innumerable cases constantly arrive at Rome, each of which demands, for its proper determination, a profound examination. These are not like cases which are submitted to the civil tribunals, in which material interests only are at stake, and for which a temporary solution is sufficient. They are questions of doctrine, which demand an answer rigorously exact, since these answers determine faith. They are questions of administration, which interest secular institutions, great personages, often entire provinces and kingdoms. They are questions of conscience, upon which depend the peace and salvation of souls. These decisions, whatever they may be, will always be received with an unqualified respect and a perfect docility, which impose upon their authors an obligation to exercise the utmost care. And yet it is also necessary to judge quickly, for the affairs are often of a vital importance which will not brook delay. It would be, of course, impossible for the sovereign pontiff to examine personally all these various matters, and to decide upon them in a single assembly. Hence the college of cardinals has been divided into a certain number of sections, to each of which pertains the examination of some particular class of cases. This division did not take place all at once. It grew into existence by the successive erection of different congregations instituted as fast and in such proportions as necessity seemed to require.
