The Triangle: in Five Series of Numbers, Part 1

The Triangle: In Five Series Of Numbers, Part 1 by Samuel Whelpley is a 19th-century religious-polemical tract framed as a series of debates within the Presbyterian and Hopkinsian controversies that roiled New York City in the early 1800s. Through the voice of the Investigator, it critiques Hopkinsian/New Divinity doctrine—the Triangle of Original Sin, Inability, and a restricted Atonement—and argues for a universal gospel invitation and genuine religious liberty. The work defends moral agency and the obligation and ability of individuals to respond to divine commands, while attacking ecclesiastical censure, sectarianism, and clerical arrogance. It treats religion as a civil and moral good and calls for reform, toleration, and the free pursuit of truth beyond sectarian bounds. Interwoven are polemical portraits of real and fictional reformers (e.g., Edwards, Hopkins, Bellamy) and satirical depictions of doctrinal authorities (Buckram). The excerpt emphasizes the value of reading primary reformers, the continuity of Reformation ideals with liberty, and the ongoing need to remove intellectual and doctrinal barriers to inquiry.
