Why the High Sparrow Threatens and Detains Cersei Lannister in Game of Thrones

In Game of Thrones, the High Sparrow's actions against Queen Cersei Lannister are not capricious but part of a broader strategy to assert the authority of the Faith Militant over the already corrupt nobility, particularly those who represent the worst examples of moral misconduct, such as Cersei.

Assertion of Faith Militant Authority

The High Sparrow, a devout leader of the Faith of the Seven, aims to cleanse the corruption within the nobility, with Cersei being a prime target. His zealous stance is a response to the moral decay that has permeated the Seven Kingdoms, and he seeks to use Cersei as a prominent example to demonstrate that no one, not even a member of the royal family, is above the law of the Faith.

Confronting Incest and Murder

The High Sparrow garners evidence of Cersei's immoral behavior, including her incestuous relationship with her brother, Jaime Lannister, and her role in the death of King Robert Baratheon. Lancel's admission of a secret affair with Cersei, and the implication that he was involved in King Robert’s murder, further tarnish her reputation and provide the High Sparrow with justification for threatening and detaining her.

The Larger Power Struggle

This confrontation is emblematic of a broader theme in the series: the exploration of the power dynamics between the church and state. The High Sparrow represents a growing influence of the Faith Militant, challenging the established power structures embodied by the Lannisters. This power struggle is not merely a local political fight but a complex battle for control over the moral and legislative authority.

Revolution and Consequences

Like many revolutions, the High Sparrow's movement seeks to replace one corrupt ruler with another. However, the High Sparrow may prove to be as tyrannical as the leaders he opposes. As a religious figure seeking to impose strict moral codes on a nation, he could easily become domineering and abusive of power.

Implications of the Current Plots

In the upcoming season, we will see Cersei confess to the incestuous relationship and undertake the Walk of Shame through King’s Landing. This event will further solidify the High Sparrow's authority and possibly intensify the ongoing power struggle between the Faith Militant and the Lannister faction. The fate of both Cersei and the remaining Lannister family will depend on the arbitrary and unpredictable decisions of those with the power to execute justice according to the Faith's strict moral codes.
