I would be curious the roots of it. Was the early church doing this?
I was wondering that myself. I used the AI in Hallow App as my starting point and will go to the primary sources for a more in-depth look and will share what I found of interest to me.
The starting point:
Fasting has deep roots in biblical tradition, was practiced by early Christians as imitation of Christ, and evolved into a structured liturgical discipline in the patristic era, particularly during Lent, as a means of spiritual combat, purification, and preparation for Easter.[^1] [^2]
### Biblical Origins
Fasting appears throughout Scripture as a practice of penance, supplication, and spiritual preparation. Moses fasted for 40 days and nights on Sinai while awaiting the Tables of the Law, symbolizing total dependence on God as the source of life: "life comes from God, that it is he who sustains it... fasting indicates that life comes from God."[^8] Jesus Himself fasted for 40 days in the wilderness, overcoming the devil's temptations, a model Christians have imitated since ancient times.[^1] The Gospels link fasting inseparably with prayer for combating evil: "This kind cannot be driven out by anything but prayer and fasting" (Mk 9:29).[^5] [^9]
### Early Church and Patristic Development
Christians fasted from apostolic times, initially as preparation for the Paschal fast on Good Friday and Holy Saturday.[^2] By the late 4th century, Lent (Quadragesima) emerged as a 40-day period of fasting. St. Jerome's letter around 384 AD is the first Roman witness to this practice, characterized by abstinence.[^2] St. Leo the Great's Lenten sermons emphasized fasting alongside virtue, linking it to almsgiving for moral renewal.[^2] [^3]
Monastics further developed fasting as spiritual combat for purity of heart, restraining body and passions: "Fasting takes hold of the entire being: the body through restraint in food and drink, and the soul through restraint of the passions."[^1] St. John Chrysostom taught holistic fasting, extending beyond food to avoid slander and sin: "Do you not eat flesh? Feed not upon indecency by means of the eyes. Let the ear fast also."[^1] In the East, the Great Fast (Lent) drew from conciliar norms like Trullo (691692).[^6]
### Liturgical Integration in Lent
Lent formalized as a 40-day fast (excluding Sundays in some traditions, like Milanese practice with preparatory weeks).[^2] [^7] Popes like Benedict XVI highlighted its role in interior purification: "Fasting... stems from the need that man has for an interior purification that detoxifies him from the pollution of sin and evil; it educates him to that healthy renunciation."[^4] It remains a core Lenten triad with prayer and almsgiving.[^3]
In summary, Christian fasting traces from biblical precedents through early asceticism to its enduring place in Lent, always as a path to holiness and union with Christ.[^1] [^2] [^4]
