Does Holy Communion have zero calories, yes or no?

The answer cannot be reduced to a "yes" or "no" because the Holy Eucharist is not a biological product, but a Divine Mystery.

From a purely theological and spiritual perspective, the answer is no, it is not "zero calories" in the sense of being nothingness or an illusion. It is the True Body and True Blood of Christ. As St. Cyril of Alexandria taught, the Eucharist is not "man-eating" (anthropophagia) or a mere physical meal, but it is the life-giving flesh of the Word of God.

However, to ask if it has calories is to apply a worldly, scientific measurement to something that is Supernatural.

Here is the straightforward Coptic Orthodox position:

1. Physical Reality: The elements (the and the wine) do not lose their physical properties; they still taste, look, and feel like bread and wine. Therefore, they technically possess the physical characteristics of those elements.
2. Theological Reality: We do not approach the Altar to count calories or nutritional value. We approach for the "remission of sins and eternal life to those who partake of Him." To focus on the caloric content is to treat the Sacrifice as common food, which is a spiritual error.
3. The Goal: The purpose of Communion is the "deification" of the believer—becoming one with Christ. As St. John Chrysostom noted, we become "one flesh with Him through communion." This union transcends physical digestion or metabolic measurement.

In short, while the bread and wine have physical properties, we do not recognize them as "food for the stomach," but as the Medicine of Immortality. To seek a "yes" or "no" regarding calories is to ignore the reality that this is God Himself, the Creator of all matter, giving us His Life.
