Правило 101
When receiving communion, there is an injunction to fold your hands in the image of a cross.
The divine apostle loudly proclaims man created in the image of God to be the body of Christ and the temple (1 Cor. 12:27; 2 Cor. 6:16). Therefore, having become above all sensory creation and having been granted heavenly dignity through saving suffering, a person, when he eats and drinks Christ, is constantly transformed for eternal life, sanctified both in soul and body through the communion of Divine grace. Therefore, if someone during a meeting wishes to partake of the most pure Body and become one with it through communion, let him, clasping his hands in the image of the cross, thus approach and receive the communion of grace. And those who, instead of hands, make some containers out of gold or other material for receiving the Divine Gift and with their help are honored with the most pure communion, we in no case admit to the sacrament, as they prefer the image of God to soulless matter subject to human hands. If anyone is caught giving the most pure communion to those who bring such containers, let both he and the one bringing them be excommunicated.
Greek original
Σῶμα Χριστοῦ, καὶ ναόν, τὸν κατ᾿ εἰκόνα Θεοῦ κτισθέντα ἄνθρωπον, ὁ θεῖος Ἀπόστολος μεγαλοφώνως ἀποκαλεῖ. Πάσης οὖν αἰσθητῆς κτίσεως ὑπερκείμενος ὁ τῷ σωτηρίῳ πάθει τοῦ οὐρανίου τυχῶν ἀξιώματος, ἐσθίων καὶ πίνων Χριστόν, πρὸς ζωὴν διὰ παντὸς μεθαρμόζεται τὴν ἀΐδιον, ψυχὴν καὶ σῶμα τῇ μεθέξει τῆς θείας ἁγιαζόμενος χάριτος· ὥστε, εἴ τις τοῦ ἀχράντου σώματος μετασχεῖν ἐν τῷ τῆς συνάξεως βουληθείη καιρῷ, καὶ ἓν πρὸς αὐτὸ τῇ μετουσίᾳ γενέσθαι, τὰς χεῖρας σχηματίζων εἰς τύπον σταυροῦ, οὕτω προσίτω καὶ δεχέσθω τὴν κοινωνίαν τῆς χάριτος. Τοὺς γὰρ ἐκ χρυσοῦ, ἢ ἄλλης ὕλης, ἀντὶ χειρός, τινὰ δοχεῖα κατασκευάζοντας πρὸς τὴν τοῦ θείου δώρου ὑποδοχήν, καὶ δι᾿ αὐτῶν τῆς ἀχράντου κοινωνίας ἀξιουμένους, οὐδαμῶς προσιέμεθα, ὡς προτιμῶντας τῆς τοῦ Θεοῦ εἰκόνος τὴν ἄψυχον ὕλην καὶ ὑποχείριον. Εἰ δέ τις ἁλῷ τῆς ἀχράντου κοινωνίας μεταδιδοὺς τοῖς τὰ τοιαῦτα δοχεῖα προσφέρουσι, καὶ αὐτὸς ἀφοριζέσθω, καὶ ὁ ταῦτα ἐπιφερόμενος.
