Purgatory

Purgatory is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Purgatory rather than just read about it. In short: Purgatory (Latin: purgatorium, borrowed into English via Anglo-Norman and Old French) is a belief in Catholic theology. It is a passing intermediate state after physical death for purifying or purging a soul before entering Heaven.

Key takeaways

  • Purgatory belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Purgatory to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Purgatory from memory before moving on to harder problems.

Reference excerpt

Purgatory (Latin: purgatorium, borrowed into English via Anglo-Norman and Old French) is a belief in Catholic theology. It is a passing intermediate state after physical death for purifying or purging a soul before entering Heaven. A common analogy is dross being removed from gold in a furnace. In Catholic doctrine, purgatory refers to the final cleansing of those who died in the State of Grace, and leaves in them only "the holiness necessary to enter the joy of heaven"; it is entirely different from the punishment of the damned and is not related to the forgiveness of sins for salvation. A forgiven person can be freed from their "unhealthy attachment to creatures" by fervent charity in this world, and otherwise by the non-vindictive "temporal (i.e. non-eternal) punishment" of purgatory. In late medieval era, metaphors of time, place and fire were frequently adopted. Catherine of Genoa (fl. 1500) re-framed the idea as ultimately joyful. It has been portrayed in art as an unpleasant (voluntary but not optional) "punishment" for unregretted minor sins and imperfect contrition (fiery purgatory) or as a joyful or marvelous final relinquishment of worldly attachments (non-fiery purgatory). The Eastern Orthodox churches have somewhat different formulations of an intermediate state. Most Protestant denominations do not endorse the Catholic formulation. Several other religions have concepts resembling Purgatory: Gehenna in Judaism, al-A'raf or the upper most layer of hell in Islam, and Naraka in Hinduism. The word purgatory has come to refer to a wide range of historical and modern conceptions of postmortem suffering short of everlasting damnation. English-speakers also use the word analogously to mean any place or condition of suffering or torment, especially one that is temporary.

History of the belief

The noun purgatory (in Latin purgatorium, a place of cleansing, from the verb purgo, 'to clean, cleanse') appeared perhaps only between 1160 and 1180, which encouraged speaking of Purgatory as a place. Purgatory pre-dates the specific Catholic tradition of purgatory as a transitional state or condition; it has a history that dates back before Christ, to related beliefs also in Judaism, that prayer for the dead contributes to their afterlife purification. The same practice appears in other traditions, such as the medieval Chinese Buddhist practice of making offerings on behalf of the dead, who are said to suffer numerous trials. The Catholic Church found specific Old Testament support in after-life purification in 2 Maccabees, which is part of the Catholic, Eastern Orthodox, Oriental Orthodox and Church of the East biblical canons, but regarded as apocryphal by Protestants and major branches of Judaism. According to the Catechism of the Catholic Church, praying for the dead was adopted by Christians from the beginning, a practice that presupposes that the dead are thereby assisted between death and their entry into their final abode. The New American Bible Revised Edition, authorized by the United States Conference of Catholic Bishops, says in a note to the 2 Maccabees passage:

This is the earliest statement of the doctrine that prayers and sacrifices for the dead are efficacious [...] The author [...] uses the story to demonstrate belief in the resurrection of the just, and in the possibility of expiation for the sins of otherwise good people who have died. This belief is similar to, but not quite the same as, the Catholic doctrine of purgatory. Sacred Tradition, by reference to certain texts of scripture, speaks of the process as involving a cleansing fire. According to Jacques Le Goff, in Western Europe toward the end of the twelfth century Purgatory started to be represented as a physical place, Le Goff states that the concept involves the idea of a purgatorial fire, which he suggests "is expiatory and purifying not punitive like hell fire". At the Second Council of Lyon in 1274, when the Catholic Church defined, for the first time, its teaching on purgatory, the Eastern Orthodox Church did not adopt the doctrine. The council made no mention of purgatory as a third place or as containing fire, which are absent also in the declarations by the Councils of Florence (1431–1449) and of Trent (1545–1563). Popes John Paul II and Benedict XVI have written that the term does not indicate a place, but a condition of existence. The Church of England, mother church of the Anglican Communion, officially denounces what it calls "the Romish Doctrine concerning Purgatory", but the Eastern Orthodox Church, Oriental Orthodox Churches, and elements of the Anglican, Lutheran, and Methodist traditions hold that for some there is cleansing after death and pray for the dead, knowing it to be efficacious. The Reformed Churches teach that the departed are delivered from their sins through the process of glorification. Rabbinical Judaism also believes in the possibility of after-death purification and may even use the word "purgatory" to describe the similar rabbinical concept of Gehenna, though Gehenna is also sometimes described as more similar to hell or Hades.

Christianity Some Christians, typically Roman Catholics, recognize the doctrine of Purgatory. The Eastern Orthodox are less likely to use the term, although they acknowledge an intermediate state after death and before final judgment, and consequentially offer prayers for the dead. Protestants usually do not recognize Purgatory as such; following their doctrine of sola scriptura, they claim Jesus is not recorded mentioning or otherwise endorsing it, and the deuterocanonical book 2 Maccabees is not accepted by Protestants as scripture.

Worked examples

Example 1 — a first encounter with Purgatory

Start with the simplest possible case. Write down what Purgatory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Purgatory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Purgatory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Purgatory

In research
Purgatory appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Purgatory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Purgatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Afterlife in Christianity, Afterlife places, Catholic terminology, so understanding it makes those chapters shorter.
In everyday life
Look for Purgatory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
