Within Catholicism in recent times, an encyclical is generally used for significant issues, and is second in importance only to the highest ranking document now issued by popes, an Apostolic Constitution. Encyclicals indicate high Papal priority for an issue at a given time. Pontiffs define when, and under which circumstances encyclicals should be issued.
