for three years in the 1620s, but resigned because of the burdens of the teaching and administration.
In 1631, Ruar moved to Gdańsk, where he was a minister in the German-speaking Socinian congregation. Known for his humanist and liberal views, Ruar was not doctrinaire and tried to reconcile Socinians with the Mennonite Remonstrants. Journeying to the Netherlands Ruar established contacts between the Polish
Arians and the Dutch
Remonstrant movement and with

Hazerswoude,
Samuel Naeranus, on the Trinity.
In 1643 Ruar had married the daughter of Martin Voss, from a well-off and prominent Gdańsk family and converted his wife, her family, friends and many citizens. These conversions did not escape the attentions of the city council, most of whom belonged to the local Lutheran Church. Following the 1638 decision of the

, the Gdańsk city council moved to exile Ruar. However, as a lawyer Ruar demanded an official trial, appealing to the support of the Polish magnates who were patrons of the
Polish Brethren. Ruar argued that the doctrine of his faith, wrongly called "Arianism," was in reality based on the Bible. The city council relented, providing Ruar was to cease converting Lutherans. After five years Ruar received from King

Ruar initially went to Warsaw, where he tried to gain support for the Socinian cause, arguing that his deportation was the beginning of religious persecution in Poland. Although he was conditionally allowed to return to Gdańsk, henceforth Ruar preferred to live outside the city, in Straszyn, where he spent the rest of his life, writing, preaching, corresponding with the congregation in Gdansk, and with scholars abroad under the protection of the hetman
Stanisław Koniecpolski. During this period he again travelled widely and freely, visiting England and Italy. He died in 1657, in
Straszyn.
Ruar was an advocate of separation of church authority from natural sciences. In 1643,
