Day 23 of Lent: The role of fasting in different Christian traditions

Lent is a sacred season observed by millions of Christians worldwide, marked by prayer, repentance, and fasting.

The Biblical and historical roots of Christian fasting

Fasting has deep biblical roots, dating back to Moses (Exodus 34:28), Elijah (1 Kings 19:8), and Jesus Himself (Matthew 4:2). Early Christians adopted fasting as a means of spiritual purification, following Christ’s example. By the 4th century, Lent emerged as a 40-day period of preparation for Easter, mirroring Jesus’ fast in the wilderness.

Over time, different Christian traditions developed unique fasting practices based on scriptural interpretation, cultural context, and ecclesiastical authority. These variations reflect both unity in purpose and diversity in expression.

1. Fasting in the Catholic tradition

The Roman Catholic Church prescribes specific fasting rules during Lent, emphasising both abstinence and moderation:

Ash Wednesday and Good Friday: Strict fasting (one full meal, two smaller meals that do not equal a full meal, no meat).

Fridays during Lent: Abstinence from meat (with exceptions for health or age).

Spiritual focus: Fasting is paired with prayer and almsgiving, forming the three pillars of Lent.

The Catholic approach balances discipline with pastoral flexibility, allowing for individual circumstances while maintaining communal observance.

2. Fasting in the Eastern Orthodox tradition

Orthodox Christians observe the Great Lent, one of the most rigorous fasting periods in Christianity:

Strict abstinence: No meat, dairy, fish, oil, or wine on most days (with exceptions for feast days).

Gradual intensity: The fast begins with Clean Monday and increases in strictness during Holy Week.

Spiritual emphasis: Fasting is seen as a means of attaining theosis (union with God), not just penance.

Orthodox fasting is deeply liturgical, with prayers and hymns reinforcing the season’s solemnity. The physical discipline is inseparable from spiritual growth.

3. Fasting in Protestant traditions

Protestant views on fasting vary widely, reflecting denominational differences:

Anglicanism: Similar to Catholicism but often less strict; emphasises personal devotion over mandated rules.

Lutheranism: Encourages voluntary fasting as a spiritual discipline, rejecting legalistic requirements.

Evangelical & Non-Denominational churches: Fasting is often individualised—some abstain from food, others from media or habits.

Many Protestants focus on the heart behind fasting (Matthew 6:16-18) rather than prescribed practices, aligning with Reformation principles of sola scriptura.

4. Fasting in other Christian traditions

Coptic Orthodox: One of the strictest fasts, with multiple extended fasting periods beyond Lent.

Syriac & Oriental Orthodox: Similar to Eastern Orthodoxy but with additional fasting seasons.

Methodism & Wesleyan traditions: Historically emphasised fasting; modern Methodists often practise it on Ash Wednesday and Good Friday.

The spiritual purpose of fasting across traditions

Despite differences, all Christian traditions agree on fasting’s core purposes:

1. Repentance & humility – Acknowledging human weakness before God (Joel 2:12).

2. Self-discipline – Strengthening resistance to temptation (1 Corinthians 9:27).

3. Solidarity with the poor – Simplifying life to focus on spiritual priorities.

4. Preparation for Easter – Purifying the heart to fully celebrate Christ’s Resurrection.
