I have a friend who is alcoholic, but still receives Holy Communion and he has never fallen off the wagon, but when in doth always consult with your spiritual father.
On one group I received this:
CAN YOU GET ILL FROM TAKING THE COMMUNION CUP?
A Physician's opinion ...to the Healing of soul and body...
By Emanuel Kolyvas, M.D., The Sign [of the Theotokos], Montreal
Contrary to popular opinion, wine, and other beverages of antiquity produced through fermentation, were probably more important in providing disease-free drinking fluids than in their tendency to intoxicate. Ancient Greeks drank their water mixed with wine, and also used wine to cleanse wounds and soak dressings. More recently, military physicians of the last century observed that during epidemics of cholera, wine drinkers were relatively spared by the disease, and troops were advised to mix wine into the water.
Wine has been shown to be an effective antiseptic even when the alcohol is removed. In fact, 10% alcohol is a poor antiseptic, and alcohol only becomes optimally effective at concentrations of 7;0%. The antiseptic substances in wine are inactive in fresh grapes because these molecules are bound to complex sugars. During fermentation these antiseptic substances are split off from the sugars and in this way become active. These molecules are polyphenols, a class of substances used in hospitals to disinfect surfaces and instruments. The polyphenol of wine has been shown to be some thirty-three times more powerful than the phenol used by Lister when he pioneered antiseptic surgery.
Same year wines can be diluted up to ten times before beginning to show a decrease in their antiseptic effect. The better wines gradually improve with age over the first ten years and can be diluted twenty times without a decrease of the antiseptic effect. This effect then remains more or less constant over the next twenty years and becomes equivalent to a new wine after another twenty-five years. (Modern antiseptics and antibiotics for disinfecting wounds have surpassed wine effectiveness because the active ingredients in wine are rapidly bound and inactivated by proteins in body tissues.)
In preparing communion, the hot water that is added to the wine will increase greatly the antiseptic effect of the polyphenols. Disinfection occurs more rapidly and more effectively at 45 degrees centigrade than at room temperature (22-25 degrees). Another contribution to the antiseptic effect comes from the silver, copper, zinc that make up the chalice itself, ensuring that microbes are unable to survive on its surface.
Throughout the centuries, no disease has ever been transmitted by the taking of Holy Communion. Diseases, such as Hepatitis B, known to be transmitted by shared eating utensils, have never been acquired from the communion spoon. HIV is known not to be transmitted through shared eating utensils, and considering the antiseptic qualities of the Holy Communion received by the faithful, there is no likelihood of acquiring HIV infection through the Common Cup.
