Saint Mother Teresa of Calcutta: A Life of Mercy and Love

Discover the extraordinary life of Saint Mother Teresa of Calcutta, founder of the Missionaries of Charity, her bond with Saint John Paul II, and her mission of love among the poorest of the poor.

From Skopje to a Missionary Vocation

Saint Mother Teresa of Calcutta was born on August 26, 1910, in Skopje, into an Albanian Catholic family, and was baptized Gonxha Agnes Bojaxhiu. Her mother's faith and practical care for those in need helped shape her vocation. At eighteen, Agnes left home to join the Sisters of Loreto in Ireland, taking the name Sister Mary Teresa in honor of Saint Thérèse of Lisieux. She arrived in Calcutta in January 1929, later teaching girls at Saint Mary's School and making her final religious profession in 1937. Her early years as a teacher laid the foundations for a life of wholehearted service.

The Call Within a Call

On September 10, 1946, while traveling by train from Calcutta to Darjeeling, Mother Teresa experienced what she later called a call within a call. She believed Jesus was inviting her to serve Him among the poorest and most abandoned people. After a period of discernment and Church approval, she left the Loreto convent in 1948 and began her work wearing the now-familiar white sari with blue borders. In December of that year she was visiting poor families, tending the sick, and helping those who had been left without care.

The Missionaries of Charity

On October 7, 1950, the Missionaries of Charity were officially established in the Archdiocese of Calcutta. The congregation grew from a local work of mercy into a worldwide religious family serving people facing homelessness, illness, loneliness, and abandonment. Mother Teresa insisted that each person be treated with tenderness and dignity, never reduced to a social problem. Prayer and the Eucharist nourished the sisters' work of charity.

Seeing Jesus in the Poorest of the Poor

Mother Teresa's service was inspired by Matthew 25:40, in which Christ identifies Himself with those who are hungry, sick, vulnerable, and forgotten. She believed that caring for another person could become a concrete expression of love for Jesus. This was not simply humanitarian activism: it was an act of Christian discipleship. Her witness calls believers to recognize the God-given dignity of every human life, especially where suffering makes people invisible to society.

Saint John Paul II and Mother Teresa: A Shared Witness to Mercy

Mother Teresa and Pope Saint John Paul II shared a profound concern for the poor and for the dignity of human life. On February 3, 1986, the Pope visited Nirmal Hriday, Mother Teresa's home for the sick and dying in Calcutta. He described it as a place where suffering met faith and love, and where each person's worth was honored. Their actual meeting inspires the artistic illustration accompanying this article; the image is a devotional interpretation, not a historical photograph. John Paul II later beatified Mother Teresa on October 19, 2003, praising her as a model of the Good Samaritan and an example of a life transformed by prayer and service.

The Eucharist, Prayer and the Thirst of Christ

Behind Mother Teresa's active work stood a deeply contemplative heart. She began her days in communion with Jesus in the Eucharist and encouraged her sisters to serve Him in suffering people. Christ's words from the Cross, I thirst (John 19:28), became central to her spirituality: she desired to respond to His love by loving those who felt unloved. For her, Eucharistic devotion and practical charity could never be separated.

A Hidden Trial of Faith

Vatican accounts of Mother Teresa's spiritual life describe a long period of interior darkness in which she experienced a painful sense of God's absence. These struggles did not erase her commitment to prayer, her vocation, or the people she served. Her experience is a reminder that personal holiness should not be confused with constant spiritual consolation. Faithfulness can be expressed through love and trust even amid suffering and uncertainty.

Recognition, Death, Beatification and Canonization

Mother Teresa received the Nobel Peace Prize in 1979, drawing worldwide attention to the needs of the poorest. She died in Calcutta on September 5, 1997. Pope Saint John Paul II beatified her in Saint Peter's Square on October 19, 2003. Pope Francis canonized her there on September 4, 2016, holding up her life as a witness to mercy. In 2025, the Holy See announced her inscription in the General Roman Calendar, establishing September 5 as her optional memorial throughout the Roman Rite.

What We Can Learn from Saint Mother Teresa Today

Her life invites us to pray before acting, recognize Christ in people who suffer, defend human dignity, offer friendship to the lonely, and practice small works of mercy with sincerity. We may not found a religious congregation, but we can visit someone who is ill, listen to a forgotten neighbor, help a struggling family, and offer our daily work to God. True charity begins when love becomes concrete.

Prayer Asking for the Intercession of Saint Teresa of Calcutta

Saint Mother Teresa of Calcutta, humble servant of Jesus Christ, teach us to recognize His presence in the poor, the sick, the lonely, and the forgotten. Intercede for our families, for those who suffer, and for all who serve people in need. Help us love the Eucharist, pray with perseverance, and respond to the thirst of Jesus with compassionate hearts. May our words and actions bear witness to the dignity of every human person. Saint Teresa of Calcutta, pray for us. Amen.
