The Canons of the Council in Trullo; Often Called The Quinisext Council 101Canon CI.

The great and divine Apostle Paul with loud voice calls man created in the image of God, the body and temple of Christ. Excelling, therefore, every sensible creature, he who by the saving Passion has attained to the celestial dignity, eating and drinking Christ, is fitted in all respects for eternal life, sanctifying his soul and body by the participation of divine grace. Wherefore, if any one wishes to be a participator of the immaculate Body in the time of the Synaxis, and to offer himself for the communion, let him draw near, arranging his hands in the form of a cross, and so let him receive the communion of grace. But such as, instead of their hands, make vessels of gold or other materials for the reception of the divine gift, and by these receive the immaculate communion, we by no means allow to come, as preferring inanimate and inferior matter to the image of God. But if any one shall be found imparting the immaculate Communion to those who bring vessels of this kind, let him be cut off as well as the one who brings them.
