From the beginning, the Church has understood that her mission is universal. Christ did not command His disciples to remain where the Gospel was already known, but to go outward—to the ends of the earth—to bring the saving message to those who had never heard His name.
Before ascending into heaven, Jesus gave the Church her missionary mandate:
“Go therefore and make disciples of all nations.”
— Matthew 28:19
This command has shaped the Church’s life for two thousand years. It is not an optional activity or a secondary concern. Mission is at the very heart of the Church’s identity.
St. Paul expresses the missionary priority of the early Church clearly in his Letter to the Romans:
“I make it my ambition to preach the Gospel, not where Christ has already been named, lest I build on another man’s foundation.”
— Romans 15:20
Paul understood that the Gospel must move outward. His missionary journeys were directed primarily toward those who had never heard the name of Jesus Christ. He traveled immense distances, endured persecution, imprisonment, and hardship because he believed that every person had the right to hear the Good News.
The apostles were not motivated by cultural expansion or political influence. They were motivated by charity—the deepest love for souls.
For if Christ truly is the Savior of the world, then withholding the Gospel from those who have never heard it would be the greatest injustice.
The Magisterium has consistently reaffirmed this missionary priority throughout the centuries.
In Evangelii Nuntiandi (1975), Pope Paul VI declared:
“The Church exists in order to evangelize.”
Evangelization is not merely one activity among many. It is the Church’s fundamental purpose. The Church lives to proclaim Christ.
The Second Vatican Council echoed this teaching in the decree Ad Gentes, which emphasizes the importance of the Church’s mission among peoples who do not yet believe in Christ. The Council taught that the Church must be present among these peoples, witnessing to the Gospel and inviting them to encounter the living God.
Perhaps the most powerful modern reflection on this mission came from Pope John Paul II in his encyclical Redemptoris Missio (1990). There he reaffirmed that the Church’s missionary task remains urgent and unfinished:
“The Church’s first duty is the proclamation of Jesus Christ to those peoples and groups who do not yet believe in Him.”
John Paul II warned that in many places missionary zeal had diminished. Yet the need for mission had not decreased—in fact, it had grown.
Billions of people still live without knowing the name of Jesus.
From the earliest centuries, the Church has been carried forward by missionaries who responded to Christ’s command.
Saint Patrick went to Ireland.
Saint Francis Xavier sailed to Asia.
Saint Junípero Serra traveled across California.
Missionaries crossed deserts, oceans, and mountains to bring the Gospel to peoples who had never heard it.
Their motivation was simple: love.
They believed that the greatest gift they could give another human being was the knowledge of Jesus Christ.
For Christ is not merely a teacher or moral guide.
He is the Savior.
And salvation is not found in programs, politics, or prosperity. It is found in Him.
Today, the missionary call remains just as urgent.
While Christianity is well established in many parts of the world, vast populations still live without ever hearing the Gospel. Entire tribes, remote communities, and isolated cultures remain outside the reach of the Church’s witness.
Often these places are geographically difficult, economically poor, or politically unstable. They are the forgotten margins of the world.
Yet it is precisely to these margins that Christ sends His Church.
The Gospel must reach not only the comfortable centers of society, but the distant villages, the rural communities, and the forgotten peoples.
The Church must go where Christ is not yet known.
In our time, missionary work often includes humanitarian service—schools, clinics, hospitals, and care for the poor. These works of mercy are essential expressions of Christian love.
But they are never meant to replace the proclamation of the Gospel.
Authentic Christian charity always points toward Christ.
To feed the hungry, heal the sick, and care for mothers and children is a profound act of love. Yet the greatest gift the Church can offer is the saving knowledge of Jesus Christ.
As Pope Benedict XVI once wrote:
“The Church does not engage in proselytism. Instead, she grows by attraction.”
When people encounter Christ through the witness of Christian love, their hearts are drawn to Him.
The world does not need more comfort.
It needs the Gospel.
It needs the hope that only Christ can give.
Every generation of Christians must decide whether they will continue the mission entrusted to the Church. The task is unfinished. The harvest remains abundant.
And somewhere in the world, there are still people who have never heard the name of Jesus.
The greatest charity we can offer them is to bring Christ where He is not yet known.
On March 4, 2016, a small home for the elderly in Aden, Yemen became the site of a quiet but powerful witness of Christian faith.
Armed militants stormed a nursing home operated by the Missionaries of Charity, the religious congregation founded by Mother Teresa. Within minutes, 16 people were killed, including four Catholic sisters who had devoted their lives to serving the most vulnerable.
Their names deserve to be remembered:
Sr. Anselm (India)
Sr. Marguerite (Rwanda)
Sr. Reginette (Rwanda)
Sr. Judith (Kenya)
These women came from different nations, cultures, and backgrounds, but they shared one vocation: to serve Christ in the poorest of the poor.
The home they operated cared for elderly men and women who had been abandoned by their families. Many were sick, disabled, or forgotten by society. The sisters did not ask about religion or background—they simply cared for them with dignity and love.
That morning began as every morning did for the Missionaries of Charity.
After Mass, before breakfast, the sisters pray St. Ignatius of Loyola’s Prayer for Generosity, a prayer that captures the heart of Christian service. It may well have been the final prayer they prayed that day:
Lord Jesus, teach me to be generous.
To serve you as you deserve;
to give and not to count the cost,
to fight and not to heed the wounds,
to toil and not to seek for rest,
to labor and not to ask for reward…
Only hours later, those words would become their reality.
During the attack, militants moved through the compound killing staff and volunteers, including several Yemeni and Ethiopian workers who helped run the home. Yet in the midst of the violence, nearly 80 elderly residents were left unharmed, a small sign of mercy in the midst of tragedy.
Also taken during the attack was Tom Uzhunnalil, a Salesian priest who had been assisting the sisters after his church was destroyed earlier in the war. He was held hostage for 18 months before finally being freed.
When news reached Rome, Pope Francis spoke about the sisters with deep emotion. He called them “the martyrs of today.” Yet he also lamented that their deaths barely appeared in the world’s headlines, describing it as part of the “globalization of indifference.”
But the Church remembers.
Their witness reminds us that the Gospel is often lived most powerfully in places the world rarely notices. These sisters did not go to Yemen for recognition, safety, or comfort. They went because they believed Christ was present in the abandoned and forgotten.
This same spirit of service continues in mission efforts around the world today.
Organizations such as Caritas Veritate Missions and LiftLife Global Health seek to carry forward that same Gospel mission: serving vulnerable communities, building healthcare access, supporting mothers and children, and bringing dignity to those who are often overlooked. www.caritasvm.org and www.liftlifeglobal.org
From maternity care initiatives in rural Africa to community health programs that protect mothers and infants, these works reflect the same truth the sisters lived: charity rooted in truth must reach the most vulnerable.
The martyrs of Aden remind us that Christian service is never merely humanitarian work. It is a witness of love grounded in the belief that every human life carries the image of God.
The sisters gave everything in that mission.
And while the world may have moved on quickly from that tragic day in 2016, their sacrifice continues to speak.
Their lives ask a question that echoes far beyond Yemen:
How far are we willing to go in serving Christ in the poor?
