Final answer:
Welde and his colleagues likely used theological debate, societal pressure, and legislative measures to attempt to change the Antinomians' belief in Antinomianism. Historical accounts do not detail their specific strategies, but broader examples include both forceful and persuasive measures to change the beliefs of various non-conforming groups.
Step-by-step explanation:
The Antinomians, notably influenced by figures such as Mrs. Anne Hutchinson, held the belief in Antinomianism which emphasized a reliance on divine grace and suggested that once grace was given, it could not be taken away, no matter the actions of the person. This set them apart from more traditional Christian beliefs that stressed adherence to moral law and behavior as an aspect of one's faith. To attempt to change the thinking of the Antimonians, those opposed, such as Welde and his colleagues, likely employed different strategies, ranging from theological debate to societal pressure and legislative measures. However, the historical context provided does not detail specific actions taken by Welde and his associates.
In a broader sense, those who sought to change the beliefs of various 'rebel' groups used a combination of forcible suppression, as seen in the violent response to slave education or indigenous resistance, and persuasion either through debate, imposition of Western thought, or the offer of inclusion and rewards, as portrayed in the hypothetical offerings provided by Washington in the fictional excerpt. In all cases, the underlying strategies involved either addressing the dissenting beliefs directly or trying to undermine them by different means, whether through force, coercion, or offering alternative benefits.
