The importance of the church in the Spanish colonial system has already been alluded to. The extent of its power and the frequency and importance of its relations with the audiencia demand considerable attention. After studying the general phases of the relations of the audiencia and the church, we shall see that the tribunal exercised ecclesiastical authority of a very pronounced character. This power it derived from two sources: first, from the authority that was entrusted to it by virtue of the royal patronage; second, from its status as a court of justice with jurisdiction in ecclesiastical affairs similar to that which it had as an ordinary tribunal of justice. The above is an outline of the plan of this book. That which impresses the modern student most with regard to Spanish administrative machinery was its failure to effect deliberately the division of powers which, with our traditions, we consider essential to a well-balanced government. The terms "executive" and "judicial" are employed in this book, as they were in Spain's colonies, to designate functions rather than departments. The viceroy, as president of the audiencia, had cognizance of certain judicial matters, and more or less participation in them, though he was forbidden to act as judge, especially over affairs in which he had already officiated as executive. The audiencia likewise shared many executive functions, yet it was not judge of its own acts, for when judgment was passed on the administrative acts or judicial pronouncements of an oidor, either on appeal or by review of sentence, that magistrate was expected to retire, or to be occupied with some other case. So, while there was no judicial department with solely judicial functions, or a legislative or executive department, as they are known in some modern states, there existed certain interrelations which did not entirely result in confusion, as one might suppose. On the contrary, it may be often noted that as a resultant of this system, men and acts of an exceedingly well-balanced and statesmanlike character were produced. We shall see, moreover, that they were far from meriting the disapprobation that is frequently heaped upon so-called Spanish governmental incapacity.
