Balius Stephen was a Polish Knight, who, like the Lubieniecius, and many other persons of distinction among his contemporaries, adopted Unitarian sentiments. He is not mentioned in the Acts of the Unitarian Church in Poland ; but we learn from Sandius, that he composed Hymns on Scriptural Subjects.
