Doug Wilson follows a key interpretive rule: the Old Testament applies today unless the New Testament specifically says it doesn't. This "applies unless revoked" view contrasts with the more common evangelical stance that the Old Testament *doesn't* apply unless the New Testament *reaffirms* it. This principle has vast implications for his views on law and society.

A key theological distinction is that Old Testament violence is descriptive, recounting historical conflicts against specific, now-extinct peoples. In contrast, the Quran's calls to violence are prescriptive and open-ended, targeting the generic category of 'the infidel.'

While appearing as a traditionalist, Khomeini's core concept, the "Guardianship of the Jurist," was a profound theological revolution. It proposed for the first time that clerics should directly rule the state, breaking with centuries of Shiite political quietism. This innovation provided the ideological basis for the new republic.

The literal meaning of jihad as 'struggle' extends beyond warfare to include non-violent methods to advance Islam's influence. These include 'jihad of the tongue' (propaganda), financial influence, and demographic competition ('baby jihad').

Islam is not merely a set of personal beliefs but a comprehensive political system. Sharia law is not a radical fringe element but the prescriptive, legal application of Islam's core tenets, making the religion inherently political.

When Jefferson and Adams asked a Barbary ambassador why they attacked American ships, he replied that the Quran commanded them to wage war on 'infidels.' This historical event serves as an early American warning about ideologically-driven conflict.

The vast majority of lands now considered the 'Muslim world,' including North Africa and the Middle East, were historically Christian territories taken by military conquest (jihad). The West often overlooks this long history of religiously motivated expansionism.

A core Islamic doctrine, 'Al-Wala' Wal-Bara'' (Loyalty and Enmity), commands Muslims to be loyal only to fellow Muslims and to harbor hatred and disavowal towards all non-Muslims. This creates a foundational 'us vs. them' worldview.

Taqiyya is the practice of permissible dissimulation, allowing a Muslim to feign friendship or even renounce their faith when under threat from non-Muslims. This doctrine makes it difficult to distinguish genuine moderates from those feigning moderation strategically.
