Sv. Cyprián a Firmilián

Není pochyb o tom, že starokalendářníci jsou heretickými donatisty, protože se dovolávávají sv. Cypriána a Firmiliána ve sporu se sv. Štěpánem I. o platnost heretických křtů z roku 255. Ve skutečnosti jak katholická ("The modern Catholic church holds dogmatically that baptism by heretics and even by atheists or other non-Christians is valid if intentionally done according to the manner that the Church prescribes and that the person doing the Baptizing be Baptised themselves. The doctrinal basis for this was articulated by St. Augustine in his conflict with the Donatists, who claimed the authority of Cyprian for their own position."), tak pravoslavná ("Baptism is not repeated, unless it was performed in a heretical Church which does not baptize in the name of the Holy Trinity." wiki: "In Orthodox Church history, examples and instances of economy abound. Since ancient times, converts to the Church who were coming from certain heretical groups were not required to be baptized, even though the normal path of entrance to the Church is through baptism. Thus the Church, guided by the Holy Spirit, decided that under specific conditions, the application of economy (i.e. according to leniency) would be the norm in this matter. But since the usual rule is baptism, such leniency can easily be, and sometimes has been, suspended (usually in periods when the heretical groups in question were actively opposing the Church). In these cases, the Church returned to her customary usual rule of "exactness," not applying economy (or not applying economy according to lenience). In calling for the reception of converts into Orthodoxy through means other than baptism in certain cases, the Ecumenical Councils made no determination regarding the existence of sacraments outside of Orthodoxy, but only addressed the situation of the convert to Orthodoxy.") církev heretické křty uznávají, pokud jsou provedeny správným způsobem.
