The Universal Brother
A Brother to Every Human Being
At the heart of Foucauld’s vocation was an ever-deepening desire to become the “universal brother” – a brother to every human being, without distinction of religion, origin, or social condition. His understanding of fraternity reached beyond the boundaries of a particular community and became a way of expressing the love of God through his own life.
This desire took concrete form during his years in North Africa. Living among people of different cultures and beliefs, Foucauld wanted Christians, Muslims, Jews, and those of no particular faith to be able to recognize in him a brother – someone who welcomed them with respect, friendship, and genuine concern for their lives.
Brotherhood, for Foucauld, was therefore not simply an idea. It was something to be lived through hospitality, friendship, service, attentive listening, and closeness to those who were poor, isolated, or forgotten. His daily relationships became the place where this vocation could take flesh.
Rather than placing words or visible results at the center of his mission, Foucauld increasingly emphasized the witness of a life shaped by goodness and love. He sought to make the Gospel visible through the way he received others and through the bonds of trust he patiently built with the people among whom he lived.
The “universal brother” would become one of the most enduring expressions of Foucauld’s spiritual legacy: the conviction that following Jesus means drawing near to every person as a brother or sister, and allowing love, presence, and friendship to overcome the barriers that separate people from one another.
Writings from Beni Abbès and Tamanrasset
Hospitality and Friendship in the Sahara
When Foucauld settled in the Sahara – first at Beni Abbès in 1901 and later at Tamanrasset among the Tuareg from 1905 – his ideal of universal brotherhood increasingly became part of the ordinary rhythm of his daily life.
Hospitality occupied a central place in this way of life. Foucauld sought to welcome those who came to him, regardless of their background or faith. Travelers, neighbors, the poor, and those in need could find food, assistance, conversation, and a place of welcome. His home was not intended to be a place of separation, but a place of encounter.
At Tamanrasset, this presence gradually developed into genuine relationships with the Tuareg. Foucauld devoted himself to learning their language and understanding their culture, while friendship and mutual trust grew through the experience of everyday life. Brotherhood was no longer simply an ideal to be pursued; it was something formed patiently through human relationships.
His writings from these years also reveal his concern for the dignity and well-being of the people among whom he lived. Although his life in the Sahara unfolded within the complex realities of the French colonial presence, Foucauld increasingly understood his own vocation in terms of closeness, service, friendship, and responsibility toward those around him.
Beni Abbès and Tamanrasset thus became places where the idea of the “universal brother” could be lived concretely: through an open door, a shared meal, a friendship patiently formed, and a presence that sought to recognize the dignity of every person.
The Association of the Sacred Heart
Living Brotherhood in Everyday Life
Foucauld’s vision of fraternity was not limited to those who might follow a religious vocation or share his life in the desert. He also developed plans for an association through which Christians, including laypeople living in the midst of ordinary society, could share in the same spirit of faith, service, and universal brotherhood.
Rather than requiring its members to withdraw from their families, professions, or communities, this project opened the possibility of living Foucauld’s spiritual intuitions within the circumstances of everyday life. Each person could seek to make the love of God visible wherever he or she was already present.
At the heart of this vision was a particular concern for those who were poor, isolated, or abandoned. Brotherhood was to be expressed through welcome, friendship, service, and attention to others – especially toward those who might otherwise be forgotten or excluded.
In this way, the ideal of the “universal brother” could extend far beyond Foucauld’s own life in the Sahara. It could become a way of living the Gospel in families, workplaces, neighborhoods, and communities, through the ordinary relationships of daily life.
Although Foucauld did not see this vision develop as he had hoped during his lifetime, the intuition would bear fruit after his death in various fraternities and associations inspired by his spirituality, allowing the call to universal brotherhood to be lived in many different forms and circumstances.
The Tuareg Dictionary and Linguistic Work
Language as a Path to Encounter
During his years among the Tuareg, Foucauld devoted an extraordinary amount of time and attention to their language and culture. He undertook extensive linguistic work, compiling a Tuareg-French dictionary and carefully collecting, transcribing, and translating traditional Tuareg poetry.
This demanding work grew out of his desire to understand the people among whom he had chosen to live. Learning their language allowed him to enter more deeply into their world, listen to their stories and traditions, and build relationships founded on greater knowledge and mutual trust.
For Foucauld, attention to another people’s language and culture was closely connected to the way he understood fraternity. To become a brother meant first drawing near, listening, learning, and taking seriously the identity and experience of the other.
His linguistic work therefore represents another dimension of his life among the Tuareg. Alongside prayer, hospitality, and friendship, years of patient study became a concrete expression of his desire to know and serve the people with whom he shared his daily life.
The dictionaries, translations, and collections he produced remain an important part of his legacy. They preserve a remarkable record of Tuareg language and oral tradition and bear witness to the depth of attention Foucauld gave to the culture of the people he had come to regard not simply as neighbors, but as friends and brothers.
Influence on 20th-Century Interfaith Thought
A Legacy of Fraternity and Encounter
Charles de Foucauld died in 1916 without seeing the religious community he had long hoped to establish. Yet the intuition at the heart of his life – becoming a brother to every person – continued to grow after his death and gradually inspired new communities, fraternities, and spiritual movements.
During the twentieth century, the Little Brothers of Jesus, the Little Sisters of Jesus, and other communities inspired by Brother Charles sought to embody this vision through lives of simplicity, prayer, work, and close presence among people of different cultures, religions, and social conditions.
His friendship with Muslims and his desire to approach every person with respect and fraternity also became an important part of his spiritual legacy. Figures such as Louis Massignon helped transmit this dimension of Foucauld’s life and contributed to a growing reflection on encounter and friendship between Christians and Muslims.
More than a century later, this vision continues to resonate within the Catholic Church. In his 2020 encyclical Fratelli Tutti, Pope Francis presented Charles de Foucauld as a man who desired to become a brother to every human being, identifying with the least in order ultimately to become the “universal brother.”
Canonized in 2022, Saint Charles de Foucauld continues to offer a powerful witness to a fraternity that crosses boundaries of culture, religion, and social condition. His legacy invites us to encounter others not first as strangers or as members of a different group, but as brothers and sisters – through presence, friendship, respect, and love.
