To understand the significance of these editions, it is necessary to go back a little in history: The papal bull Unigenitus (1713) takes up and perfects the various bulls against "Jansenist heresy" by particularly condemning the theses of Quesnel and Arnauld, it would give rise to a religious dispute in France that would gradually worsen into a major political crisis over confession tickets and refusal of sacraments to those who opposed the bull. Not only would the French clergy be divided, but Parliament itself would go on strike and oppose the king in this matter, who had ordered the application of the bull. The confrontation between parliament and the king would last more than 20 years. The bull Unigenitus gave new vigor to a moribund Jansenism, thus causing the opposite effect.
