Правило 29
Anathema to those who follow Jewish religious customs and celebrate Saturday instead of Sunday.
That Christians should not practice Judaism and abandon their work on the Sabbath. But let them work on this day, and on Sunday, giving preference to this day as Christians, leave all work if they can. If there are any Judaizers, let them be anathema from Christ.
Greek original
Ὅτι οὐ δεῖ Χριστιανοὺς ἰουδαΐζειν καὶ ἐν τῷ σαββάτῳ σχολάζειν, ἀλλ᾽ ἐργάζεσθαι αὐτοὺς καὶ ἐν τῇ αὐτῇ ἡμέρᾳ· τὴν δὲ Κυριακὴν προτιμῶντας, εἴγε δύναιντο, σχολάζειν ὡς Χριστιανοί. Εἰ δὲ εὑρεθεῖεν Ἰουδαϊσταί, ἔστωσαν ἀνάθεμα παρὰ Χριστῷ.
