Of the line of twenty-three bishops the most distinguished were George Enyedi (1592–1597), whose "Explicationes" obtained European vogue, and Mihály Lombard de Szentábrahám (1737–1758), who rallied the forces of his Church, broken by persecution and deprivation of property, and gave them their traditional statement of faith. His "Summa Universae Theologiae Christianae secundum Unitarios" (published 1787), Socinian with Arminian modifications, was accepted by Joseph II as the official manifesto of doctrine, and so remains, though subscription to it has not been required since the 19th century. The first secondary school in Transylvania was established in the late 18th century in Székelykeresztúr (Cristuru Secuiesc); this functions to this day, although as a state school. The official title in Hungary is the Hungarian Unitarian Church, with a membership of about 25,000 members, whereas in Romania there is a separate church with the name of Unitarian Church of Transylvania and about 65,000 members, especially among the "Székely" population. In the past, the Unitarian bishop had a seat in the Hungarian parliament. The principal college of both churches is located at Cluj-Napoca ("Kolozsvár"), which is also the seat of the Transylvanian consistory; there were others at Turda ("Torda") and at Cristuru Secuiesc. Until 1818 the continued existence of this body was largely unknown to English Unitarians ; relations subsequently became intimate. After 1860 a succession of students finished their theological education at Manchester College, Oxford; others at the Unitarian Home Missionary College. In England Unitarianism was a protestant sect that had its roots in the Anabaptist radicals of the English Civil War. They adopted adult baptism, and Godly republicanism; and they were egalitarians who sought to promote extreme revolutionary ideals. The movement gained popularity among dissenting nonconformists in the early 18th century. English Presbyterians were attracted to the second city at Norwich, by its emerging scientific community, which in the wake of the Enlightenment was particularly strong in Scotland. They began to become a formal denomination in 1774 when Theophilus Lindsey organized meetings with Joseph Priestley, founding the first avowedly Unitarian congregation in the country, at Essex Street Church in London.
