Moscorovius, Hieronymus a Polish Unitarian writer of note, flourished towards the close of the 16th or about the opening of the 17th century. He was a nobleman and a lay worker in the Church. He is supposed to have died about 1625. He is distinguished especially as the joint author (with Valentine Schmalz, a Socinian minister) of the larger Socinian Catechism, which was published in the Polish tongue (1605, 12mo). It was translated into Latin under the title: Catechesis Ecclesiarum, quae in regno Polon. et magno ducatu
Lithuaniae et aliis ad istud regnum pertinentibus provinciis affirmant, neminen alium praeter patrem domini nostri J.C. esse illum unum Deum Israelis, hominem autem illum, Jesum Naz., qui ex virgine natus est, nec alium praeter aut ante ipsum, Dei filium unigenitumn et agnoscunt et confitentur (Ravoc. 1609, 12mo): a new edition, together with a refutation, was published by G.L. Oeder (Francf. and Leips. 1739, 8vo); here the questions are for the first time numbered. This Catechism was ordered to be burned by the Parliament of England in 1652. It was translated, with notes and illustrations, and a sketch of the history of Unitarianism, by Thomas Rees (Lond. 1818). See extracts in Gieseler, Eccl. Hist. 4:367 sq.
