Here’s the latest I can confirm about Pasquier Quesnel from reputable sources:
Pasquier Quesnel (1634–1719) was a French Jansenist theologian who led the Jansenist movement after Antoine Arnauld’s death, facing strong opposition from both secular and papal authorities. He spent his later years in the Dutch Republic, dying in Amsterdam in 1719. These details are consistently reported by standard reference works, including Britannica and Catholic Encyclopedia. [Britannica: Pasquier Quesnel][Catholic Encyclopedia: Pasquier Quesnel]
His most influential work, the Morale Reflections on the New Testament (Réflexions morales sur le Nouveau Testament), was central to Jansenist literature and later condemned by the papacy in the bull Unigenitus (1713), marking a severe setback for Jansenist toleration within Catholicism. This sequence is described in Britannica and other encyclopedic entries. [Britannica: Pasquier Quesnel][Wikipedia: Pasquier Quesnel]
After being banished from Paris and eventually arrested, Quesnel escaped to Amsterdam where he continued writing in support of Jansenist ideas until his death; his life is summarized in multiple historical references. [Britannica: Pasquier Quesnel][Catholic Encyclopedia: Pasquier Quesnel]
