Today, we celebrate a special occasion in the life of the Church: the 100th anniversary of World Mission Sunday, established by Pope Pius XI in 1926. This year’s theme, chosen by Pope Leo XIV, is “One in Christ, United in Mission.” For a century, Catholics throughout the world have united in prayer, sacrifice, and generosity to support the Church’s missionary work, especially in communities where the Gospel is still being proclaimed for the first time, a process called primary evangelization.
In today’s Gospel, the Pharisees ask Jesus whether it is lawful to pay taxes to Caesar. Their question is a trap, but Jesus answers wisely: “Repay to Caesar what belongs to Caesar and to God what belongs to God.” Jesus reminds us that we have responsibilities as citizens of our country, but our ultimate allegiance belongs to God. We must be responsible citizens, respect legitimate authority, and work for the common good. Yet God deserves more than our money or occasional prayers; He deserves our hearts, our lives, and our faithful service.
The first reading reminds us that God is the Lord of history. He chooses Cyrus, a foreign ruler, to accomplish His saving purpose. This teaches us that God’s mission extends beyond nationalities, cultures, and boundaries. God can work through unexpected people and circumstances to bring His light to the world. Therefore, the Church’s mission is universal, and every person is invited to encounter the saving love of God.
In the second reading, Saint Paul praises the Thessalonians for their work of faith, labor of love, and endurance in hope. Their faith was not merely something they professed; it was visible in their lives and strengthened by the Holy Spirit. This is what it means to be one in Christ and united in mission. Our unity must be more than gathering in the same church; it must be expressed through love, mutual support, forgiveness, and a shared commitment to proclaiming the Gospel.
World Mission Sunday reminds us that mission belongs to every baptized Christian. We do not all have to travel to distant countries to be missionaries. We can proclaim Christ in our families, workplaces, schools, and communities through our words, our example, and our service to those in need. We also support missionaries around the world through our prayers and financial contributions, helping them bring the Gospel, education, healthcare, and hope to vulnerable communities.
As we celebrate this historic centenary, let us give to God what belongs to God by offering Him our hearts and our lives. United in Christ, may we continue the mission entrusted to us, so that people everywhere may encounter His love and come to know the joy of the Gospel.
