Pope Shenouda III
Our aim should always be to fast out of love for God.
Out of love, we desire that our souls adhere to Him. We do not allow our bodies to hinder the way of the soul. Therefore, we subdue through fasting to make the body conform with the soul in its work. It is in fasting that we are likely to soar above the materialistic and bodily needs, and live by the soul. To allow the human soul to unite in God's Spirit in His work to enjoy His love and company.
