Hierarchy

Is the Catholic Church a hierarchical church?

Yes, it is.

In the Catholic Church's hierarchy, a priest is subject to the authority of his bishop, and both priests and bishops are subject to the authority of the pope.

Style notes:

Typically, references to "the hierarchy" or to "the institutional church" refer to higher-level Church officials and offices, such as those that comprise the Roman Curia, rather than lower-level Church officials such as parish priests.
