  • On the 22nd of January 1556, a Polish student named Piotr of Goniądz stood before the general synod of Reformed churches in the village of Secemin. He spoke out against the doctrine of the Trinity during that gathering. This moment marked the beginning of what would become known as the Minor Reformed Church of Poland. The Calvinist leaders present did not accept his arguments at the time. A theological debate called by King Sigismund II Augustus took place in 1565 to try to bring both Protestant factions together again. That effort failed to unite them. Finally, on the 10th of June 1565, the faction supporting Piotr broke all ties with the Calvinists. They organized their own synod in the town of Brzeziny.

  • Their biggest cultural centers were located in the towns of Pińczów and Raków. These places housed the main Arian printing press and the university known as the Racovian Academy. The academy was founded in 1602 and operated until it closed in 1638. Over one thousand students received training within its walls. The institution became a major intellectual center for non-trinitarian thought across Europe. Books printed there spread ideas about religious tolerance and rational religion far beyond Polish borders. The physical buildings stood as symbols of a community that valued education alongside faith.

  • The Minor Church in Poland was dissolved on the 20th of July 1658 when the Sejm expelled the Socinians from the country. This decision came after a series of seventeenth-century wars known as the Deluge. During these conflicts, Protestant Sweden invaded Poland. The Brethren were commonly seen as Swedish collaborators because they did not participate in military service like other citizens. The expulsion sent refugees into three different directions. Some found asylum in the Duchy of Prussia where Krzysztof Crell-Spinowski and his sons founded new congregations. Others moved to the Netherlands where Andrzej Wiszowaty Sr. published works under the title Bibliotheca Fratrum Polonorum quos Unitarios vocant in 1668. A third group settled in Transylvania where the Unitarian Church enjoyed freedom. Andrzej Wiszowaty Jr. later became a teacher at the Unitarian College in Kolozsvár.

  • They were against capital punishment and rejected traditional Christian doctrines such as Hell or the Trinity. Their adherents refused military service entirely. They were known for carrying wooden swords instead of the real almost obligatory szablas. Members also declined to serve in political office. They advocated the separation of church and state while teaching the equality and brotherhood of all people. Social privileges based on religious affiliation were opposed by their community. Originally, the Minor Church followed a non-trinitarian doctrine inspired by writings from Michael Servetus. Later on, Socinianism named for Italian theologian Fausto Sozzini became its main theological approach. These core beliefs defined daily life and public conduct for every member of the fellowship.

  • After being expelled from Poland, they emigrated to England, East Prussia and the Netherlands. Their works were widely published there and influenced much of the thinking of later philosophers. John Locke was preceded by decades of work on tolerance by Samuel Przypkowski. Andrzej Wiszowaty contributed ideas about rational religion that reached English thinkers. Isaac Newton had met Samuel Crell, son of Johannes Crellius from the Spinowski family. Newton collected many books from the Racovian Academy and was well informed about developments in Poland. The Englishman John Biddle translated two works by Przypkowski as well as the Racovian Catechism. He also translated a work by Joachim Stegmann who was described as a Polish Brother from Germany. Biddle's followers maintained very close relations with the Polish Socinian family of Crellius.

  • During the Second Polish Republic, priest Karol Grycz-Śmiałowski recreated what he considered a revival of the Church of Polish Brethren in Kraków in 1937. During the People's Republic of Poland, it was registered in 1967 as the Unity of Polish Brethren. Modern groups that look to the Polish Brethren include the Christadelphians and Church of God General Conference. Although Christadelphians had always looked for historical precedents since their origins in the 1840s, they were unaware of closer precedents in Socinianism until later. That changed with a series of articles published in the community magazine during the early 1970s. The Polish arm of the Christadelphians uses the name Bracia Polscy in a conscious echo of Socinian precedents. The Atlanta Bible College of the Church of God General Conference publishes a Journal continuing research into related groups.
