What is "encyclicals"

Usage examples of "encyclicals".

I never read the proclamations of generals before battle, the speeches of fuehrers and prime ministers, the solidarity songs of public schools and left-wing political parties, national anthems, Temperance tracts, papal encyclicals and sermons against gambling and contraception, without seeming to hear in the background a chorus of raspberries from all the millions of common men to whom these high sentiments make no appeal.
