Context paragraphs:
Penitential canons: Penitential canons are religious rules laid down by councils or bishops concerning the penances to be done for various sins.  These canons, collected, adapted to later practice, and completed by suitable directions formed the nucleus of the "Penitential Book"s (see Moral Theology).

Alessandro Verde: Alessandro Verde (27 March 1865 – 29 March 1958) was an Italian Roman Catholic Cardinal and former Archpriest of the Basilica di Santa Maria Maggiore.

De fisco Barcinonensi: De fisco Barcinonensi ("Concerning the Barcelonian Fisc") is a letter ("epistola") from a group of bishops in the province of Tarraconensis in the Visigothic Kingdom to the treasury agents in Barcelona.  The letter reminds the officials of the fixed rate of public tribute and demands that exactions in excess of that amount should stop.  In the manuscripts, "De fisco" is preserved after the acts of the Second Council of Barcelona of 540, but its signatories are mostly those of the acts of the First Council of Zaragoza of 592.  Most scholars believe it should be dated in connexion with the latter council.  The bishops describe themselves as "all [those] who contribute to the fisc of the city of Barcelona", but the bishop of Barcelona, Ugnas, did not sign.  The location of the regional fiscal administration in Barcelona perhaps explains why that city survived the Islamic conquest better than the provincial capital, Tarragona.

Frederik Harhoff: Frederik Harhoff (born May 27, 1949) is a Danish jurist.  He was born in Copenhagen.  He was a member of the faculty of the University of Copenhagen.  He served as an "ad litem" judge for the International Criminal Tribunal for the former Yugoslavia from January 9, 2007 to August 28, 2013.  After acquittals of mid-level Serbian suspects in war crimes trials, Harhoff circulated a letter to colleagues stating that the higher bar for convictions in this case was established by ICTY Chief Justice Theodor Meron, and strongly hinted that Meron was acting on behalf of the U.S. and Israel in enacting the policy (Harhoff later said, unconvincingly, that he had erred in not including Russia, France and China amongst countries that would actively seek higher standards for war crimes because all three countries were involved in controversial military operations at the time).  The Harhoff letter was highly controversial when it was leaked to the press, and Harhoff was disqualified from a separate war crimes trial for being set on conviction regardless of evidence, later departing the ICTY when his term of office was not renewed there.  Harhoff whined to a Danish newspaper that he "knew" none of his friends would give the letter to a tabloid they didn't read, and implied with no supporting evidence that the leak was the result of his being "spied on".

On the Pastoral Care of Homosexual Persons: The document On the Pastoral Care of Homosexual Persons, also known by its opening words "Homosexualitatis problema", was a pastoral letter authored by the Congregation for the Doctrine of the Faith (CDF) of the Roman Catholic Church addressed to the Bishops of the Catholic Church that was delivered in Rome on 1 October 1986 by Cardinal Joseph Ratzinger (later Pope Benedict XVI) and Archbishop Alberto Bovone.  The letter gave instructions on how the clergy should deal with and respond to lesbian, gay, and bisexual people.  Pope John Paul II approved the letter and ordered its publication.  It was designed to correct misunderstandings and misinterpretations of a 1975 CDF letter, "Declaration on Certain Questions Concerning Sexual Ethics" ("Persona Humana").

Lansing Main Street Historic District: The Lansing Main Street Historic District is a nationally recognized historic district located in Lansing, Iowa, United States.  It was listed on the National Register of Historic Places in 2014.  At the time of its nomination the district consisted of 51 resources, including 42 contributing buildings, 8 non-contributing buildings, and one non-contributing site.  The district covers most of the central business district, which is generally along Main Street.  The commercial buildings are mostly masonry structures constructed with bricks or native limestone.  A few buildings are frame construction with gable roofs.  The buildings are from one- to three-stories in height, although most are no taller that two stories.  The Italianate architectural style dominates.  Most of the upper stories in the buildings housed retail or office space, but a few were residential.  The commercial buildings that did not house retail establishments were located near the Mississippi River and were industrial in nature.  The G. Kerndt & Brothers Office Block (1861) and the G. Kerndt and Brothers Elevator and Warehouses, No. 11, No.12 and No. 13 (1868) are individually listed on the National Register.  Three public buildings are located in the district: the former jail and fire station (ca. 1855-1865), the Art Deco former City Hall (1938), and the modern U.S. Post Office (c. 1960).

Economic Justice for All: "Economic Justice for All" is the pastoral letter promulgated by the United States Conference of Catholic Bishops in 1986.  It deals with the U.S. economy and with Catholic social teaching in the U.S. context.  It is a part of the tradition of Catholic social teaching.  The letter was written at a time when the Reagan administration was implementing libertarian policies of laissez-faire capitalism, and it may be interpreted as a reaction to what was seen as hostility towards the Catholic Church's teachings on social justice, subsidiarity, corporatism and distributism.
