He preached an early form of socialist utopianism, including community assets and common work.
He claimed that the true Christians, that is the Polish Brethren, did not need a State, which was created only for evil people to control and punish them.

The majority followed the views of Fausto Sozzini, advocated by Grzegorz Paweł z Brzezin and the Silesian Georg Schomann who denied the pre-existence of Christ, though they still accepted the virgin birth of Jesus, unlike later Unitarianism.
In 1568 Grzegorz Paweł z Brzezin translated into Polish the commentary on the first chapter of the Gospel of John, by Fausto Sozzini.
