Like Bellarmine Suarez was a man of great personal piety, well versed in the writings of the Fathers and in the literature of the Reformers. His works are clear and well arranged but somewhat too diffuse. The last edition (Vives) of his works was published at Paris (1856-61). /John de Lugo/ (1583-1660) was born at Madrid, went to Salamanca to study law, and there joined the Jesuits. He lectured first at Valladolid, and later on at Rome where he attracted crowds of students, and he was created cardinal in 1643. In his works he has covered practically the entire field of dogmatic and moral theology. The best known are perhaps /De Justitia et Jure/ and his treatises on the Incarnation, the Sacraments, the Eucharist, and the Sacrifice of the Mass. The last edition of his published works was issued at Paris (1868-9). /Dionysius Petavius/[5] (Petau, 1583-1652) was born at Orleans, studied arts and theology at Paris, entered the Society of Jesus (1605), and taught theology at Paris for twenty-two years. He was one of the best known and most respected scholars of his age. Quite apart from his merits as a theologian, his works on chronology, notably the /De doctrina temporum/ and the /Tabulae Chronologicae/ would have been sufficient to place him in the first rank of the scholars of his period. In theology he is chiefly remarkable for the introduction and application of the historical method in his discussion of dogma, and hence he is referred to rightly as the "Father of the History of Dogma." His principal theological work is the /Dogmata Theologica/ (1644-50). The splendid example of a scientific treatment of moral theology set by St. Thomas produced very little effect during the fourteenth and fifteenth centuries, for the simple reason that the /Sentences/, and not the /Summa/, was the text-book used generally in the schools. Following along the lines marked out by Raymond of Penafort in his /Summa de poenitentia et matrimonio/ (1235) a large number of /Summae/ or manuals for the use of confessors were published during the fourteenth and fifteenth centuries, the last of them being that of Silvester Prierias, one of the earliest opponents of Luther. One of the few writers of this period who undertook to give a scientific explanation of moral principles is St. Antoninus (1389-1459), the Dominican Archbishop of Florence, in his /Summa Theologica Moralis/.
