Introduction:
In a time when the entire world is facing a serious ecological crisis, many solutions are proposed by science, politics, and social movements. But rarely does the voice of Christian Tradition rise as a prophetic response. Yet the saints — those great lovers of God — were already living a form of “integral ecology” long before it became fashionable. What do St. Francis of Assisi, St. Hildegard of Bingen, St. Benedict, the Curé of Ars, or St. John Paul II have to say about responsible use of goods, simplicity of life, and care for our common home?
This article doesn’t aim to offer “green” advice like the world does, but to recover a spiritual and theological vision that helps us live with simplicity, reverence, and love… not just for nature, but for the Creator.
Ecological austerity is not a trend: it is a call to conversion of heart.
1. St. Francis of Assisi: Live as a brother, not an owner
“Praised be You, my Lord, through our Sister Mother Earth, who sustains and governs us and produces various fruits with colored flowers and herbs” (Canticle of the Creatures).
St. Francis was not a modern environmentalist but a deeply Catholic mystic. His love for creatures was not based on romantic sentimentality, but on the certainty that all creation reflects God’s glory. He did not worship nature — he regarded it as another sibling in the great family of the Father.
St. Francis’ advice:
Detach yourself from consumerism. Live with what is necessary. Learn to be thankful and to care for what you have as if it were a sacred gift. Excess possessions suffocate the soul. Franciscan austerity is a liberation, not a loss.
Practical application:
- Do a lifestyle examination: do you really need everything you buy?
- Donate or give away what you don’t use.
- Try small consumption fasts: a week without buying anything beyond essentials.
2. St. Hildegard of Bingen: Listen to the harmony of creation
Physician, prophetess, theologian, and Doctor of the Church, Hildegard had a profoundly organic view of the universe. For her, sin not only breaks our relationship with God — it also disrupts all of creation. She taught that the human being is called to collaborate with divine wisdom (“viriditas,” the green force of God) by maintaining both interior and exterior balance.
St. Hildegard’s advice:
Care for your body, your soul, and your surroundings as a living temple. Do not waste vital energy. Learn to eat in moderation, work with purpose, and live in peace with your environment.
Practical application:
- Examine your eating habits: eat with attention, without gluttony.
- Practice a “time ecology”: organize your day without unnecessary haste; seek silence and sabbath rest.
- Grow a plant, tend a small garden, or reconnect with natural cycles.
3. St. Benedict of Nursia: “Ora et labora” in balance
St. Benedict didn’t write an ecological encyclical, but his famous Rule — which guided generations of monks — contains a spirituality of work, humility, and respect for things. In his monasteries, everything had its place: silence, manual labor, cleanliness, liturgy, farming.
St. Benedict’s advice:
Don’t despise what is small or ordinary. Make every act an offering pleasing to God. Live with order, sobriety, and common sense. The soul is shaped in the concrete.
Practical application:
- Organize your home and life like a monastery: clean, reduce, structure your time.
- Give thanks for the objects you use: don’t break or discard them lightly.
- Use what you have until the end before buying more.
4. St. John Mary Vianney (the Curé of Ars): Love poverty to be free
The Curé of Ars lived in radical austerity. His clothes were old, his meals meager, and he shared everything he had with the poor. He didn’t do this out of contempt for material things, but out of love for God. He knew that the lighter one lives, the easier it is to rise to heaven.
St. John Vianney’s advice:
Be austere not to feel superior, but to be more available to God and others. Everything you possess can become a chain. Live lightly, love much.
Practical application:
- Voluntarily give up some habitual luxury (desserts, extra heating, unnecessary driving).
- Offer your discomfort as penance for the world.
- Learn to repair rather than throw away.
5. St. John Paul II: Human and spiritual ecology
In his encyclical Centesimus Annus and other addresses, St. John Paul II warned about the damage to nature caused by a utilitarian view of humanity. But he also insisted that there is no true ecology without an ecology of the heart — that is, without a man reconciled with God and with himself, the world will continue to be exploited.
“Respect for life, and especially for human life, is the first step toward a proper use of creation” (John Paul II, Evangelium Vitae).
St. John Paul II’s advice:
Protect life in all its forms, especially human life. Live with moral responsibility. Educate in respect, solidarity, and service.
Practical application:
- Defend life from the womb to natural death.
- Be responsible with your use of resources: water, energy, paper.
- Teach children gratitude and care for what they use.
A theological vision: What is ecological austerity?
From a Catholic perspective, ecological austerity is not just a sober lifestyle — it is a concrete expression of the commandment to love. The world was entrusted to man so that he might “cultivate and care for it” (Genesis 2:15), not exploit it without conscience. Original sin broke this harmony, but in Christ it can be restored.
To live austerely is also to do penance. In a world wounded by excess and waste, every small sacrifice offered with love has redemptive power. The Christian doesn’t just “avoid polluting”: he offers his life as a liturgy — a lived Eucharist.
A practical pastoral guide for living ecological austerity today:
- Ecological Examination of Conscience
- Am I grateful for what I have?
- Do I buy out of need or impulse?
- How many resources do I consume and waste each day?
- Simple and Concrete Personal Commitments
- Use less plastic, recycle, buy local.
- Turn off unnecessary lights and devices.
- Pray before consuming, as a conscious act.
- Spiritual Dimension
- Offer ecological sacrifices as acts of love.
- Join cleanup initiatives, community gardens, or help those in need.
- Contemplate creation as a “natural cathedral” where God speaks.
- Family and Community
- Teach children responsible use of resources.
- Celebrate with sobriety: less waste in parties, more community spirit.
- Transform your home into a small monastery of prayer, work, and balance.
Conclusion:
The saints didn’t live in the era of plastic or climate change, but they left us a wisdom more urgent today than ever. They understood that caring for creation is also caring for the soul. And that living with less — when done out of love for God — does not impoverish, but enriches.
Today the world needs not just environmentalists, but ecological saints. Men and women who live evangelical poverty, respect for life, the joy of simplicity, and the contemplation of the Creator in all created things.
“Creation waits in eager expectation for the children of God to be revealed” (Romans 8:19)
