Some context: Jonah or Jonas is the name given in the Hebrew Bible (Tanakh/Old Testament) to a prophet of the northern kingdom of Israel in about the 8th century BCE. He is the eponymous central figure of the Book of Jonah, in which he is called upon by God to travel to Nineveh and warn its residents to repent of their sins or face divine wrath. Instead, Jonah boards a ship to Tarshish. Caught in a storm, he orders the ship's crew to cast him overboard, whereupon he is swallowed by a giant fish.
Jonah is regarded as a saint by a number of Christian denominations. His feast day in the Roman Catholic Church is on 21 September, according to the Martyrologium Romanum. In Catholicism, the Book of Jonah is also read aloud in its entirety on Maundy Thursday in a Beneventan chant. On the Eastern Orthodox liturgical calendar, Jonah's feast day is on 22 September (for those churches which follow the traditional Julian calendar; 22 September currently falls in October on the modern Gregorian calendar). In the Armenian Apostolic Church, moveable feasts are held in commemoration of Jonah as a single prophet and as one of the Twelve Minor Prophets. Jonah's mission to the Ninevites is commemorated by the Fast of Nineveh in Syriac and Oriental Orthodox Churches. Jonah is commemorated as a prophet in the Calendar of Saints of the Missouri Synod of the Lutheran Church on 22 September. Christian theologians have traditionally interpreted Jonah as a type for Jesus Christ. Jonah being in swallowed by the giant fish was regarded as a foreshadowing of Jesus's crucifixion and the fish vomiting Jonah out onto the beach was seen as a parallel for Jesus's resurrection. Saint Jerome equates Jonah with Jesus's more nationalistic side, and justifies Jonah's actions by arguing that "Jonah acts thus as a patriot, not so much that he hates the Ninevites, as that he does not want to destroy his own people." Other Christian interpreters, including Saint Augustine and Martin Luther, have taken a directly opposite approach, regarding Jonah as the epitome of envy and jealousness, which they regarded as inherent characteristics of the Jewish people. Luther likewise concludes that the kikayon represents Judaism, and that the worm which devours it represents Christ. Luther's antisemitic interpretation of Jonah remained the prevailing interpretation among German Protestants throughout early modern history. J. D. Michaelis comments that "the meaning of the fable hits you right between the eyes", and concludes that the Book of Jonah is a polemic against "the Israelite people's hate and envy towards all the other nations of the earth." Albert Eichhorn was a strong supporter of Michaelis's interpretation. John Calvin and John Hooper regarded the Book of Jonah as a warning to all those who might attempt to flee from the wrath of God. While Luther had been careful to maintain that the Book of Jonah was not written by Jonah, Calvin declared that the Book of Jonah was Jonah's personal confession of guilt. Calvin sees Jonah's time inside the fish's belly as equivalent to the fires of Hell, intended to correct Jonah and set him on the path of righteousness. Also unlike Luther, Calvin finds fault with all the characters in the story, describing the sailors on the boat as "hard and iron-hearted, like Cyclops", the penitence of the Ninevites as "untrained", and the king of Nineveh as a "novice". Hooper, on the other hand, sees Jonah as the archetypal dissident and the ship he is cast out from as a symbol of the state. Hooper deplores such dissidents, decrying: "Can you live quietly with so many Jonasses? Nay then, throw them into the sea!"
What were their post-biblical views?

Some context: James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans. The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.) Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.
