Canon 101 Communion received in the hands, not vessels

The divine Apostle loudly calls man, created according to the image of God, the body of Christ and a temple. Standing, then, above all sensible creation, he who through the saving Passion has attained the heavenly dignity, eating and drinking Christ, is continually refashioned for eternal life, being sanctified in soul and body by partaking of the divine grace; so that, if anyone wishes to partake of the immaculate body at the time of the synaxis, and to become one with it by participation, let him, forming his hands in the figure of a cross, so approach and receive the communion of grace. For those who make certain receptacles of gold or other material, instead of the hand, for the receiving of the divine gift, and by them are counted worthy of the immaculate communion, we in no way admit, as preferring lifeless and subordinate matter to the image of God. And if anyone is caught imparting the immaculate communion to those who bring such receptacles, let him be excommunicated, both he and the one who brings them.
