Character analysis
St. Thomas Aquinas
in Letter from Birmingham Jail by Martin Luther King Jr.
St. Thomas Aquinas appears in Martin Luther King Jr.'s "Letter from Birmingham Jail" not as a character in a story but as a key philosophical authority that King references to support civil disobedience against unjust laws. King directly cites Aquinas's distinction—found in his Summa Theologica—between just laws, which align with eternal and natural law, and unjust laws, which harm human dignity and lack moral legitimacy. By invoking Aquinas, King roots his argument in the Western Catholic intellectual tradition, appealing to the white clergymen's own theological background to show that resisting immoral laws is not lawlessness but a higher form of obedience.
Aquinas stands as a cornerstone of King's moral framework. His ideas enable King to assert that segregation laws are unjust because they cause spiritual and psychological damage to Black Americans, relegating them to a lower status in the eyes of God and society. For King, this is not just theoretical theology; it provides a direct justification for the intentional, nonviolent law-breaking in the Birmingham campaign.
As a rhetorical figure, Aquinas embodies intellectual credibility, Christian orthodoxy, and centuries of moral thought. His presence indicates that King's stance is neither radical nor new—it aligns with the most esteemed traditions of Western Christianity. Aquinas thus plays a crucial role in King’s argument: transforming the label of "extremist" that the clergymen used against him into a badge shared with respected thinkers throughout history.
