The lectionary swaps the Old Testament reading for a passage from Acts during the entire Easter season. Most Catholics walk into Mass, hear the reading, and walk out without thinking about it again. That is a missed opportunity. Acts is not background material. It is the only document that records how the apostles actually built the Church after the Resurrection, and the questions it answers are questions modern Catholics rarely hear addressed directly.
The first thing Acts does is settle the question of whether the apostles understood what had happened. Chapter 2 records Peter standing up in front of a Pentecost crowd and preaching a homily that quotes Joel, names Jesus by his hometown, and accuses the audience of crucifying him. Three thousand people are baptized that day. The Peter who denied Jesus three times in the courtyard is not the Peter who preaches at Pentecost. Something happened between those two scenes, and Acts treats the change as the central evidence that the Resurrection was real and the Spirit was at work.
The second thing Acts does is record the first arguments inside the Church. Chapter 6 is about the Greek-speaking widows being neglected in the daily food distribution while the Hebrew-speaking widows were taken care of. The apostles do not pretend the problem is not real. They appoint seven men to handle the distribution and free themselves to preach. The structure of the early Church was not a spiritual abstraction. It was built around real complaints from real people, and the response was practical.
Chapter 15 is the council of Jerusalem, which is the most important administrative meeting in Christian history. The question on the table was whether Gentile converts had to follow the full Mosaic law to become Christians. Paul and Barnabas argued no. James, the leader of the Jerusalem community, sided with them. The decision sent in a letter to the Gentile churches is the first recorded exercise of magisterial authority in the Church. Catholics who want to understand why the Church can teach with binding authority should read Acts 15 carefully.
The travel narratives in chapters 13 through 28 are the founding documents of Christian missiology. Paul plants a church in Philippi after meeting Lydia, a wealthy textile dealer, at a riverside prayer gathering. He plants one in Thessalonica after preaching in the synagogue for three weeks. He plants one in Corinth that meets in the house of a tentmaker named Aquila and his wife Priscilla. The pattern is consistent. The early Church grew through hospitality, through household connections, and through the willingness of ordinary people to host strangers.
The final chapters record Paul's arrest, his trials, and his journey to Rome. The shipwreck in chapter 27 is one of the most detailed nautical accounts in ancient literature, and it ends with Paul preaching the Gospel on the island of Malta while waiting for a ship to take him to Rome for trial. The book ends abruptly with Paul under house arrest in Rome, still preaching. Luke does not record his death. The implication is that the story is not finished, that the work begun in Acts is the work the Church is still doing.
The practical case for reading Acts during Easter is that the season is fifty days long, and the book has 28 chapters. A chapter a day with two days off per week covers the entire book between Easter and Pentecost. The reading takes about twelve to fifteen minutes per chapter for someone reading at a normal pace. The Easter season ends with Pentecost, which is the event Acts opens with, so the timing creates a circular reading that ties the liturgical calendar to the text.
The Catholic Bible commentary tradition on Acts is substantial. Father Luke Timothy Johnson's commentary in the Sacra Pagina series is the most rigorous scholarly treatment available in English. Father Mitch Pacwa's audio commentary on EWTN covers the book at a more accessible pace. The Ignatius Catholic Study Bible includes a complete Acts volume with footnotes that connect the book to current Catholic teaching. None of these resources requires a theology degree to follow.
The Diocese of Nashville parishes have been programming Acts study groups during Easter season for the past three years. Saint Henry Parish ran a Tuesday evening group in 2024 and 2025 that drew 47 to 62 attendees per session. The Cathedral of the Incarnation runs a Sunday morning group between Masses. Saint Edward in Donelson runs a parking lot study during warm weather. The model is consistent across parishes. One chapter per week, about 45 minutes of discussion, with a parishioner facilitator and a parish priest available for theological questions.
The book is not difficult to read. It is one of the most narrative-driven texts in the New Testament, with named characters, specific cities, and scenes that move quickly. The investment is small. The payoff is a real understanding of how the Church started, why it is structured the way it is, and what the apostles actually expected the Christian life to look like after Jesus returned to the Father. Most Catholics have never read Acts straight through. The Easter season is the natural time to do it.
