Background

An encyclical (from Latin encyclia, from the Greek "en kyklo, ἐν κύκλῳ", meaning "general" or "encircling") was a circular letter sent to all the churches of a particular area in the ancient Christian church. 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. A Papal 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.

The title of a Papal Encyclical is usually taken from its first few words.

View of Pope Pius XII

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. He wrote in Humani generis:

It is not to be thought that what is set down in Encyclical letters does not demand assent in itself, because in this the popes do not exercise the supreme power of their magisterium. For these matters are taught by the ordinary magisterium, regarding which the following is pertinent: “He who heareth you, heareth Me.” (Luke 10:16); and usually what is set forth and inculcated in Encyclical Letters, already pertains to Catholic doctrine. But if the Supreme Pontiffs in their acts, after due consideration, express an opinion on a hitherto controversial matter, it is clear to all that this matter, according to the mind and will of the same Pontiffs, cannot any longer be considered a question of free discussion among theologians.

The use of encyclicals by Pius XII

Encyclicals indicate high Papal priority for an issue at a given time. Only pontiffs define when, and under which circumstances encyclicals should be issued. They may choose to issue an apostolic constitution, bull, encyclical, apostolic letter or give a papal speech. Pontiffs differ on the use of encyclicals. On the issue of birth control and contraception, for example, Pope Pius XI issued the encyclical Casti connubii, while Pope Pius XII spoke to midwives and the medical profession when he clarified his position on the issue.^[1] Pope Paul VI published an encyclical Humanae vitae on the same topic. On matters of war and peace, Pope Pius XII issued ten encyclicals, most of them after 1945, three of them (Datis nuperrime, Sertum laetitiae, and Luctuosissimi eventus) protesting the Soviet invasion and crackdown of the Hungarian revolution in 1956. Pope Paul VI spoke about the war in Vietnam and Pope John Paul II, issued his protest against the war in Iraq in speeches. On social issues, Pope Leo XIII promulgated Rerum novarum, followed by Quadragesimo anno by Pius XI, and Centesimus annus by John Paul II. Pius XII spoke on the same topic to a consistory of cardinals in his Christmas messages and to numerous academic and professional associations.^[2] The magisterium of Pius XII is therefore significantly larger than the below listed 41 encyclicals. Most of the detailed teachings are in his papal speeches on specific topics such as:

Conscience, guilt and fair punishment,^[3]
Ethics of psychological research,^[4]
Farmers,^[5]
Fashion Industry,^[6]
Formation of conscience,^[7]
Genetic research,^[8]
Human dignity,^[9]
Medical doctors and the use of weapons,^[10]
Military medical research,^[11]
