That which is especially remarkable about these institutions is the protection which they give to private interests, since the submission of each affair to the scrutiny of many persons is a security for knowledge, independence, and impartiality in its decision. Moreover, these institutions preserve the customs and the character of an ecclesiastical government. We have mentioned the relationship of bishops and their chapters. Every chapter was subdivided into commissions, to each of which a separate part in the administration of the diocese was assigned. One had the spiritual and scholastic direction of the episcopal seminaries; another, that of the temporalities; and still another, the examination and reception of the candidates for the priesthood. These commissions bear a certain resemblance to the Roman congregations. The latter were established by the voluntary action of the sovereign pontiffs. The Council of Trent was not occupied with them. It regulated diocesan administration as it believed useful, but it left the administration of the universal church to the wisdom of the popes; so that precisely at the time when its enemies think they can detect tendencies on the part of the holy see to absolutism, the pontiffs without constraint, but of their own accord, organize those institutions which are the best safeguards against the dangers of absolute power. In reckoning up the number of those who, under different titles, take part in these labors, we discover that the Roman congregations form an entire assemblage of five hundred persons, all illustrious for their piety and learning. Many councils have been less numerous. These constitute a sort of permanent council, which is in daily communication with all the churches of the world, and which, not being limited in duration, can bring to the questions which are submitted to it all desirable deliberation. Perfect order presides over its labors. Like the councils, it is divided into sections, to which the members are assigned according to their peculiar aptitudes. These sections, which are the congregations properly so called, are permanent also, and consequently are enabled to devote themselves to the study of all the branches of ecclesiastical administration for the purpose of determining its principles. Finally, like the councils themselves, they draw their authority from the sovereign pontiff, and their decisions are subject to his approval. The attributes of these congregations are manifold and various. They may be arranged under three principal heads: administrative, deliberative, and judicial.
