Holy Scripture reveals many spiritual benefits of fasting.
But why does fasting bring about all these benefits?
Why is abstinence from food so important?
I believe one of the answers is a simple one.
In the Garden of Eden, we lost our purity by prematurely indulging in an illicit meal.
Thus, it is fitting to regain our purity by patiently abstaining from food.
The meal shared by Adam and Eve was self-centered, in rebellion against God.
The Christian fast shared by the Church is Christ-centered, in submission to God.
The most rewarding fast is on Sunday mornings and on great feast days. We fast from all food and drink. We willingly forego feeding ourselves, until Christ himself feeds us with his holy body and blood in the Eucharist.
Thus salvation comes to us by the same means as the fall. By means of food.
