Virginity and chastity before marriage is demanded and expected for Christians. It is the most healthy sexuality that gives bliss to the body, advanced athletic ability, and easeful and quick growth of musculature. To disagree is to become demonic, making other Christians knowing your position incapable of eating at the same table with you according to First Corinthians 5:11. It is the way into heaven, for the half hearted prayer of a virgin can move mountains, can stop wars, and can change the cosmos. It can also acquire mercies within a second before falling asleep that others unchaste would need ten years of prayer upon their knees to acquire and more so to preserve.
It is not as though it is a great act or obedience. What is great is St. Paul’s rage at those who commit sexual immorality with their bodies with others. Those he casts out of church and places in the hands of Satan until the flesh has suffered fires and purgation.
