Ewangelicko-reformowany katechizm krakowski a katechizmy wileńskie Stanisława Sudrowiusza i Jana Zygrowiusza

Comparison of Reformed Protestant catechisms printed for the Lesser Poland Congregation and the Lithuanian Congregation highlights the theological differences, which were splitting these two communities till the beginning of the 17th century. The Lithuanian Congregation was influenced by the antitrinitarian propaganda, which manifested in the rigorous avoidance of the phrase “Holy Trinity” in the community’s teachings (and, most probably, in sermons). This period of the hidden antitrinitarian influence on the Lithuanian Congregation was ended by the catechism by Jan Zygrowiusz, published in Lubcz in 1618.
