Correction of the Euchologion

2. Philip IV, Catholic King of the Spains, towards the beginning of 1631, had recourse to the Apostolic See. He revealed that he had been informed by Greek Uniate inhabitants of this realm that a Euchologion containing many errors had been published by the Greek schismatics; he asked at that time for the application of appropriate remedies to this source of foolish confusion. At once Urban VIII formed a special Congregation for the correction of the Euchologion and personally appointed to it certain Cardinals, Prelates of the Roman Curia, and renowned theologians. At that time, he summoned to Rome others with a worldwide reputation for ecclesiastical learning, intending to appoint them also to this Congregation. Among those summoned was Dionysius Petavius, a priest of the Society of Jesus living in France; however, he understandably excused himself from so long a journey because of his advanced age. Jean Morin, a priest of the Gallican oratory, was also called to Rome; he attended many sessions and made many noteworthy proposals which aided the organization and direction of the undertaking. These We will discuss in another place.
