Canon 9
On the excommunication until repentance of heretics visiting cemeteries to pray.
That members of the Church are not allowed to visit the cemeteries of heretics or the so-called tombs of martyrs for prayer or healing, and those who do so, if they are faithful, should be deprived of fellowship for some time. Those who repent and confess their error are accepted into fellowship.
Greek original
Περὶ τοῦ μὴ συγχωρεῖν εἰς τὰ κοιμητήρια, ἢ εἰς τὰ λεγόμενα μαρτύρια πάντων τῶν αἱρετικῶν ἀπιέναι τοὺς τῆς ἐκκλησίας, εὐχῆς ἢ θεραπείας ἕνεκα· ἀλλὰ τοὺς τοιούτους, ἐὰν ὦσι πιστοί, ἀκοινωνήτους γίνεσθαι μέχρι τινός. Μετανοοῦντας δέ, καὶ ἐξομολουμένους, ἐσφάλθαι, παραδέχεσθαι.
