The first instance of it is in the early ages, either as a Jewish Gnostic sect, Ebionitism, or in some of the other forms of Gnosticism; passing in the east into Arianism, which lowered God, and in the west into Pelagianism, which elevated man. For this period see F. Lange, Geschichte und Lehrbegriff d. Unitarier vor d. Nicaenischen Synode, 1831; Hagenbach's Dogmengeschichte, § 23; and the church histories which treat of this period.
In the middle ages the tendency may be considered to be mainly represented by Mahometanism, and hardly exists at all in the Christian church.
Its modern form arises at the time of the Reformation.
1. Originating in Italy, it exists as a doctrine in Switzerland and Germany from 1525-1560. See F. Trechsel's Die Protest. Antitrinitarier vor Faustus Socinus, 1844. The best known names are Servetus, Lelio Sozini, and Ochino.
2. It exists as a church at Racow in Poland, where the exiles found a refuge. Here Faustus Sozinus (1539-1603), nephew of Lelio, and J. Crellius, are the best known names. In 1609 Schmelz drew up the Socinian Formula, the Racovian Catechism. It was also here that the collection of Socinian writers, the Bibliotheca Fratrum Polonorum, 1626, was published. The history of the sect up to this point may be found in the Introduction to Rees's Translation of the Racovian Catechism, 1818. Also see Hallam's History of Literature, i. 554. ii. 335; Mosheim's Church History, sixteenth century, §2. P. ii. ch. iv; Hase's Church History (Engl. Transl.), § 371, 2. The Socinians were driven out of Poland in 1658, by the influence of the Jesuits; and, passing into Holland, became absorbed in the church of the Remonstrants or Arminians.
3. The next stage of Socinianism is, as a doctrine, in England in the seventeenth century. In 1611 two persons, Hammont and Lewis, suffered martyrdom for it; and it spread widely during the [pg 392] Long Parliament. (See Dr. Owen's Vind. Evangel. pref.) The chief teacher was J. Biddle (1615-1662). The interest of it arises from its supposed parallelism to the Arminianism of Hales in the time of Charles I, and to the latitudinarian party of Whichcote and More in that of Charles II. But the parallel is not quite correct. The study of Arminius's writings (see J. Nicholls's translation, 1825,) shows that he was not a Pelagian,[1061] if even his successors were. But even Episcopius and Limborch hardly reached this point. Hales resembled Episcopius. Nor is the parallel much nearer with “the latitude men;” for Socinianism lacked their Platonizing tendency. The Arian tendency, which commenced at the end of the century, both in the church, in such writers as Whiston and Clarke, and among the presbyterians, offers a nearer parallel, in being, like Socinianism, Unitarian in tendency. On this period see Hagenbach's Dogmengesch. (Notes to § 234.)
4. Its next form, was as a set of congregations in England in the eighteenth century, chiefly arising out of the presbyterians; marked by great names, such as Lardner, Lowman, Priestley.[1062] Shortly before the close of the century, it was introduced into America.
5. Its last form is a modification of the old Socinian view, formed under the pressure of evangelical religion on the one side and rationalist criticism on the other. The accomplished writers, Channing in America and Mr. J. Martineau in England, are the best types of this form. Priestley, Channing, and Martineau, are the examples of the successive phases of modern Unitarianism: Priestley, of the old Socinianism building itself upon a sensational philosophy; Channing, of the attempt to gain a larger development of the spiritual element; Martineau, of the elevation of view induced by the philosophy of Cousin, and the introduction of the idea of historical progress in religious ideas. In reference to this part of the history see E. Renan's Essay on Channing, Etudes de l'Hist. Relig. p. 357; E. Ellis's Half Century of Unitarian Controversy (in America), 1858; J. J. Taylor's Retrospect of Religious Life in England, 1845; Dr. Beard's Unitarianism in its Actual State; and other references given in the notes to H. B. Smith's translation of Hagenbach's Dogmengesch. New York, 1862. ii. p. 441.
In addition to the above references, materials for the history will be found in Sandius, Biblioth. Antitrin. 1684; Bock's Hist. Antitrin. 1774; Otto Foch's Der Socinianismus, &c. 1847; and an article in the North British Review, No. 60, for May 1859. The history of the controversial literature on the subject is given in Pfaff's Introd. in Hist. Theol. Lit. vol. ii. p. 320 seq.; and more fully in Walch's Biblioth. Theol. Select. vol. i. p. 902 seq. For a [pg 393] digest of the arguments used in the controversy, see Hoornbeek's Summa Controv. 1653, p. 440; J. Fabricius, Consid. Var. Controv. pp. 99-208; and Stapfer's Inst. Theol. Polem. vol. iii. c. 12.
