Правило 84
The need to annually announce to all the churches of proconsular Africa, after the general council convened in Carthage, the day on which the Resurrection of Christ was to be celebrated this year.
It was desirable that the day of the adored Easter be announced to everyone through a postscript under the definitions of the Council. And let the day of the Council remain the same as it was determined at the Council of Ippon, namely: 10 days before the September calendar. It is also necessary to write to the leaders of all regions so that when they convene the Council, they have this day in mind.
Greek original
Ὁμοίως ἤρεσεν, ὥστε τὴν ἡμέραν τοῦ προσκυνητοῦ Πάσχα διὰ τῆς τῶν τετυπωμένων ὑπογραφῆς πᾶσιν ἐμφανίζεσθαι. Ἡ δὲ τῆς συνόδου ἡμέρα ἡ αὐτὴ φυλαχθῇ, ἥτις ὡρίσθη ἐν τῇ ἐν Ἱππῶνι συνόδῳ, τουτέστιν, ἡ πρὸ δέκα καλανδῶν Σεπτεμβρίων· ὀφείλει γὰρ καὶ γραφῆναι πρὸς τοὺς πρωτεύοντας πασῶν τῶν ἐπαρχιῶν, ἵνα, ὅτε παρ᾽ ἑαυτοῖς σύνοδον προσκαλοῦνται, ταύτην τὴν ἡμέραν φυλάττωσι.[1]
