An Historical Account of Two Notable Corruptions of Scripture is a dissertation by the English Mathematician and Scholar Isaac Newton. First published in 1754, twenty-seven years after Newton's death, it reviewed all the textual evidence available from ancient sources on two disputed Bible passages, at 1 John 5:7-8 and 1 Timothy 3:16.

Summary of both passages
Newton did not publish these findings during his lifetime, likely due to the political climate. Those who wrote against the doctrine of the Trinity were subject to persecution in England. As late as 1698 the Act for the Suppression of Blasphemy and Profaneness made it an offense to deny one of the persons of the Trinity to be God, punishable with loss of office, employment and profit on the first occasion, and imprisonment for a repetition. Newton's friend William Whiston (translator of the works of Josephus) lost his professorship at Cambridge for this reason in 1711. In 1693 a pamphlet attacking the Trinity was burned by order of the House of Lords, and the next year its printer and author were prosecuted. In 1697 Thomas Aikenhead, an eighteen-year-old student charged with denying the Trinity, was hanged at Edinburgh, Scotland.
