The controversy in the Spanish Netherlands was only the prelude to a much more serious conflict in Spain itself. In 1588 the well-known Jesuit, Luis de Molina (1535-1600) published at Lisbon his celebrated work, /Concordia liberi arbitrii cum gratiae donis etc./ with the approbation of the Dominican, Bartholomew Ferreira, and the permission of the Inquisition. Hardly had the work left the printing press than it was attacked warmly by Domingo Banez (1528-1604), the friend and spiritual director of St. Teresa, and one of the ablest Dominicans of his time. He had been engaged already in a controversy with the Jesuit, Montemaior, on the same subject of Grace, but the publication of Molina's book added new fuel to the flame, and in a short time the dispute assumed such serious proportions that bishops, theologians, universities, students, and even the leading officials of the state, were obliged to take sides. The Dominicans supported Banez, while the Jesuits with some few exceptions rallied to the side of Molina. The latter's book was denounced to the Inquisition, but as a counterblast to this Banez also was accused of very serious errors. If Molina was blamed for being a Semi-Pelagian, Banez was charged with having steered too closely to Calvinism. In the hope of restoring peace to the Church in Spain Clement VIII. reserved the decision of the case to his own tribunal (1596). To get a grasp of the meaning of the controversy, it should be borne in mind that in all theories concerning the operation of Grace three points must be safeguarded by all Catholic theologians, namely, man's dependence upon God as the First Cause of all his actions natural as well as supernatural, human liberty, and God's omniscience or foreknowledge of man's conduct. Following in the footsteps of St. Thomas, the Dominicans maintained that when God wishes man to perform a good act He not only gives assistance, but He actually moves or predetermines the will so that it must infallibly act. In this way the entire act comes from God as the First Cause, and at the same time it is the free act of the creature, because the human will though moved and predetermined by God acts according to its own nature, that is to say, it acts freely. In His eternal decrees by which God ordained to give this premotion or predetermination He sees infallibly the actions and conduct of men, and acting on this knowledge He predestines the just to glory /ante praevisa merita/. According to this system, therefore, the efficaciousness of Grace comes from the Grace itself, and is not dependent upon the co-operation of the human will.
