Eight sermons before the Sejm

[5] After a number of quarrels, the Sejm failed to pass any legislation, even those related to national security; some suspected that foreign powers bribed some deputies to ensure this outcome.

[5] In the Sermons, Skarga discusses what he sees as the problems of the ailing Commonwealth: lack of love for the Fatherland, internal quarrels, tolerance of "heretics", the relative powerlessness of the king, problematic laws (a critique of the Golden Freedoms) and immorality.

[8] Skarga's prediction of the country's fall, combined with the quality of his prose, led to his recognition as a "patriotic seer".

[8] Inconvenient historical context – such as that Skarga blamed religious tolerance as one of the chief evils, and incorrectly saw the Muslim Ottoman Empire as the Polish–Lithuanian Commonwealth's primary threat – was swept aside by the positive reviews and endorsements of numerous 19th-century historians, as well as artists, most notably poet Adam Mickiewicz and painter Jan Matejko, the latter immortalizing Skarga on his painting Kazanie Skargi (Skarga's Sermon).

[10] The same year Berga published a monograph about Skarga, Un prédicateur de la cour de Pologne sous Sigismond III, Pierre Skarga, 1536-1612: étude sur la Pologne du XVIe siècle et le protestantisme polonaise.
