Ash Wednesday the first day of Lent. On this day, the observance of fast and abstinence begins. Pope St. Leo teaches that the main purpose for fasting is not that the body be deprived of food, but that the mind at the same time be withdrawn from wickedness, we should endeavor during Lent, not only to be temperate in eating and drinking, but especially to lead a modest life, sanctifying the days by persevering prayer and devoutly attending the Church’s liturgy.
