An 'encyclical' was a circular letter sent to all the churches of a particular area in the ancient Christian church. At that time, the word could be used of a letter sent out by any bishop. The word comes from Latin ''encyclia'' (from the Greek "en kyklo, ") meaning "general" or "encircling", which is also the origin of the word "encyclopedia".
The Roman Catholic Church generally only uses this term for papal encyclicals, but the Eastern Orthodox Church and the Anglican Communion retain the older usage.

Roman Catholic usage

For the modern Roman Catholic Church a 'Papal encyclical', in the strictest sense, is a letter sent by the Pope which is explicitly addressed to Roman Catholic bishops of a particular area or to the world, usually treating some aspect of Catholic doctrine. However, the form of the address can vary widely, and often designates a wider audience. Papal encyclicals usually take the form of a Papal brief due to their more personal nature as opposed to the formal Papal bull. Papal encyclicals are so famous that the term ''encyclical'' for Roman Catholics is used almost exclusively for those sent out by the Pope. The title of the encyclical is usually taken from its first few words.
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. However, the designation 'encyclical' does not always denote such a degree of significance. The archives at the Vatican website currently classify some encyclicals as "Apostolic Exhortations". This informal term generally indicates documents with a broader audience than the bishops alone.
Pope Pius XII held that Papal Encyclicals, even when they are not ''ex cathedra'', can nonetheless be sufficiently authoritative to end theological debate on a particular question:
