The Ascension of the Lord is not merely a past event marking the conclusion of Christ’s earthly ministry. Rather, it remains part of the living mystery of Christ that continues to unfold in the life of the Church. As the final movement of the Resurrection, the Ascension is deeply connected to Easter and filled with hope and promise. Unlike historical figures who belong only to the past, Jesus Christ transcends history. Though his words are preserved in Sacred Scripture and his saving works proclaimed through the Church’s tradition, Christ himself remains alive and present among his people. Through the Ascension, his presence was not lost but transformed, for he now dwells continually within the Church, wherever the Gospel is preached, the sacraments celebrated, and believers gather in his name.
The First Reading from the Acts of the Apostles highlights both the promise and mission entrusted to the disciples. Before ascending into heaven, Jesus assures them that they will receive the power of the Holy Spirit and become his witnesses to the ends of the earth. As they stand gazing upward in amazement, the messengers in white challenge them: “Why are you standing there looking at the sky?” Their question shifts the disciples’ attention from passive wonder to active mission. The time for simply watching has ended; the time for proclaiming Christ to the world has begun.
In the Gospel of Matthew, Jesus makes this mission clear when he commands his followers to go forth, make disciples of all nations, baptize, and teach. Yet this mission is strengthened by his enduring promise: “I am with you always, until the end of the age.” Here lies the mystery of the Ascension — though Christ is no longer visibly seen, he is closer than ever through the life and witness of his Church. He continues to speak through his people and act through their faithful service. Since this mission is greater than human strength alone, the Ascension also prepares the way for the coming of the Holy Spirit at Pentecost, who deepens Christ’s presence within believers. Therefore, Christians are not called to remain looking upward, but to go into the world, teach the Gospel, and become living witnesses of what they proclaim.
