Besides Bellarmine, “the best controversial writer of his age” (Bayle), the Roman Catholic Church numbers among its noted modern theologians:—Petavius (1583-1652), whose dogmatic theology Gibbon calls “a work of incredible labor and compass”; Melchior Canus (1523-1560), an opponent of the Jesuits and their scholastic method; Bossuet (1627-1704), who idealized Catholicism in his Exposition of Doctrine, and attacked Protestantism in his History of Variations of Protestant Churches; Jansen (1585-1638), who attempted, in opposition to the Jesuits, to reproduce the theology of Augustine, and who had in this the powerful assistance of Pascal (1623-1662). Jansenism, so far as the doctrines of grace are concerned, but not as respects the sacraments, is virtual Protestantism within the Roman Catholic Church. Moehler’s Symbolism, Perrone’s “Prelectiones Theologicæ,” and Hurter’s “Compendium Theologiæ Dogmaticæ” are the latest and most approved expositions of Roman Catholic doctrine. (_b_) Arminius (1560-1609), the opponent of predestination. Among the followers of Arminius (1560-1609) must be reckoned Episcopius (1583-1643), who carried Arminianism to almost Pelagian extremes; Hugo Grotius (1553-1645), the jurist and statesman, author of the governmental theory of the atonement; and Limborch (1633-1712), the most thorough expositor of the Arminian doctrine. (_c_) Laelius Socinus (1525-1562), and Faustus Socinus (1539-1604), the leaders of the modern Unitarian movement. The works of Laelius Socinus (1525-1562) and his nephew, Faustus Socinus (1539-1604) constituted the beginnings of modern Unitarianism. Laelius Socinus was the preacher and reformer, as Faustus Socinus was the theologian; or, as Baumgarten Crusius expresses it: “the former was the spiritual founder of Socinianism, and the latter the founder of the sect.” Their writings are collected in the Bibliotheca Fratrum Polonorum. The Racovian Catechism, taking its name from the Polish town Racow, contains the most succinct exposition of their views. In 1660, the Unitarian church of the Socini in Poland was destroyed by persecution, but its Hungarian offshoot has still more than a hundred congregations. 4. _British Theology_, represented by: (_a_) The Baptists, John Bunyan (1628-1688), John Gill (1697-1771), and Andrew Fuller (1754-1815).
