Paul, David a celebrated Polish Unitarian divine, flourished near the middle of the 16th century. In 1563 he took part in a discussion against the Lutherans at Weissenburg, and was so persuasive in his arguments that the princes and the chief nobles of the country embraced his doctrines. There is scarcely anything else known of his history. See Krasinski, Hist. of the Ref. in Poland, 1:356.
