The Racovian Catechism (Pol.: Katechizm Rakowski) is a nontrinitarian statement of faith from the 16th century. The title Racovian comes from the publishers, the Polish Brethren, who had founded a sizeable town in Raków, Kielce County, where the Racovian Academy and printing press was founded by Jakub Sienieński in 1602.
The Polish Brethren or Ecclesia Minor were an antitrinitarian minority of the Reformed Church in Poland who had separated from the Calvinist majority, or Ecclesia Major in 1565.
Several authors had a hand in drafting the Catechism: Valentinus Smalcius, Hieronim Moskorzowski, Johannes Völkel and others. It is likely that some of the text had been prepared by the Italian exile Fausto Sozzini, who had settled among the Polish Brethren in 1579, without ever formally joining, and who died in the year before the Catechism was drafted. Despite his lack of any official status in the church Sozzini had been influential in bringing the Polish church round to a Christology which closely resembled what he had learnt from his uncle Lelio Sozzini in exile in Switzerland as a young man.
The Racovian Catechism was published in 1605, and subsequently translated into other languages. Smalcius produced a German version.
The Ecclesia Minor survived in Poland until 1656 when it was outlawed by the Polish Sejm in the Roman Catholic Counter-Reformation. These nontrinitarians, and their Catechism, would later become known as Socinians due to the prominence given to Fausto Sozzini's writings after his death in the series Bibliotheca Fratrum Polonorum published in Amsterdam 1665 and widely circulated in England and elsewhere.
