The Jesuit edition is based on the third edition of Newton's Principia (1687), by the minim frias Thomas Le Seur (1703-1770), François Jacquier (1711-1788), both of whom were French priests, and Jean-Louis Calandrini (1703-1758), a Swiss mathematician. This edition includes several commentaries, explanations and addendums to the Principia that did not originate with Newton. The editors of the "Jesuit Edition", made use of the formalism developed by Leonhard Euler (1707-1783), outlined in his work Mechanica (1736), to rewrite Principia's propositions into differential equations.
Notably, the commentators "1) explain Newton's propositions in a clearer manner than Newton did; 2) translate the properties given by Newton geometrically in more analytical terms; 3) sometimes explain the development of physics, based on Newton's discoveries, after Newton" (Bussotti and Pisano, 2014a, 35-36). Le Seur, Jacquier and Calandrini accomplished these tasks magnificently.
