No, it’s an issue of penance and reparation, as well as keeping the spirit as ruling the body, rather letting the body rule the spirit.
'Therefore, brethren, we are debtors, not to the flesh, to live according to the flesh.
For if you live according to the flesh, you shall die: but if by the Spirit you mortify the deeds of the flesh, you shall live.’
Romans 8:12-13
'Exterior mortification is the conquering of the sensual appetites.
Worldlings call the saints cruel, because they deny their bodies all sensual gratifications, and afflict themselves with hair-shirts, disciplines and penances.
But St. Bernard says that those are much more cruel towards themselves, who for the sake of the momentary pleasures of this world, condemn themselves to the eternal torments of the next. Others say that the body should be denied all forbidden pleasure, but despise exterior mortifications, saying that interior mortification alone is necessary, that is, the mortification of the will. Yes, it is in the first place necessary to mortify the will, but it is also necessary to mortify the flesh; because if the flesh be not mortified, it will have great difficulty in being obedient to God.
St. John of the Cross says, that he who teaches that exterior mortification is not necessary is not to be believed, although he should perform miracles. ’
St. Alphonsus Maria de Liguori
