On his parents' advice he moved to Kraków from Silesia in 1558 and studied classics, where in 1559 he received a master's degree in Philosophy.

Here Wujek completed a master's degree in Philosophy and supplemented his philosophical studies with mathematical lectures and learning Greek.

In 1565 he joined the Jesuit Order in Vienna and after novitiate he began theological studies at Collegium Romanum where he received a doctor's degree.

Wujek's translation of the New Testament first appeared in 1593, complete with "teachings and warnings" regarding the Brest Bible and the Socinian versions of Symon Budny and Marcin Czechowic.

His translation is precise and multilateral; its language is easy and clear whilst at the same time serious and dignified.
