Canon 5
About anathema to those who teach to disdain temples and public church services.
If anyone teaches that the house of God and the congregation therein can easily be neglected, let him be anathema.
Greek original
Εἴ τις διδάσκοι, τὸν οἶκον τοῦ Θεοῦ εὐκαταφρόνητον εἶναι, καὶ τὰς ἐν αὐτῷ συνάξεις, ἀνάθεμα ἔστω.
