Reformation marked the beginning of a particular period for the Catholic Church which was connected with the necessity to provide codification and unification of the Church’s discipline also in terms of liturgy. The resolutions of the Council of Trent and the books issued by its order were directly brought into use in the whole Church. The final adoption of the Council’s resolutions in Poland took place in 1564. During the synods, many of which were held within the walls of Saint James’s Church in Piotrków, the clergymen took action aiming at stopping the development of Protestantism in Poland – inter alia Confessio catholicae fidei Christiana announcement and the order to issue Polish adaptation of Rituale Romanum – Rituals of Piotrków. This book contained the rules which concerned performing cult, with particular reference to national customs. It also included the regulations referring to keeping birth certificate registries.
