Correct Option: C. St. Luke Detailed Explanation: The Acts of the Apostles, often referred to simply as Acts, is a book in the New Testament of the Christian Bible. It is widely accepted among scholars and theologians that this book was authored by St. Luke, who is also credited with writing the Gospel of Luke. Here’s a step-by-step breakdown of why St. Luke is the correct answer:

1. Authorship Attribution:
2. The title "Acts of the Apostles" suggests a narrative about the actions of the apostles after the ascension of Jesus Christ. Early church tradition attributes this work to Luke, a physician and companion of the Apostle Paul.
3. The opening verses of Acts (Acts 1:1-2) indicate that the author is the same person who wrote the Gospel of Luke. The author addresses "Theophilus," which is a name that appears in both the Gospel and Acts, suggesting continuity in authorship.
4. Historical Context:
5. St. Luke is known to have been a well-educated Gentile, and his writings reflect a sophisticated understanding of Greek language and culture. This aligns with the style and content of Acts, which includes detailed accounts of the early church's growth and the spread of Christianity beyond Jewish communities.
6. Content and Themes:
7. The book of Acts focuses on the actions of the apostles, particularly Peter and Paul, and the early Christian community. It emphasizes the work of the Holy Spirit and the expansion of the church, themes that are consistent with Luke's theological perspective as seen in his Gospel.
8. Historical Evidence:
9. Early church fathers, such as Irenaeus and Eusebius, recognized Luke as the author of Acts. This historical consensus supports the claim of St. Luke's authorship.

Why the Other Options are Incorrect:

• A. The Apostle, Paul:
• While Paul is a significant figure in Acts, especially in the latter chapters, he is not the author. Acts serves as a historical account of his missionary journeys but does not reflect his personal authorship. Paul wrote several letters (epistles) in the New Testament, but Acts is not one of them.
• B. Peter, the Apostle:
• Peter is another key figure in Acts, particularly in the early chapters where he leads the Jerusalem church. However, like Paul, he did not write Acts. The narrative includes Peter's actions but is not authored by him.
• D. Theophilus:
• Theophilus is mentioned in the opening of both the Gospel of Luke and Acts as the person to whom these works are addressed. He is not the author but rather a recipient of the writings. The name "Theophilus" means "friend of God," and it is unclear whether this refers to a specific individual or a broader audience.

Revision Summary:

• The Acts of the Apostles was written by St. Luke, who is also the author of the Gospel of Luke.
• The book addresses Theophilus, indicating a connection between the two works.
• Acts details the early church's growth and the apostles' actions, particularly focusing on Peter and Paul.
• Historical evidence and early church tradition support St. Luke's authorship, while the other options (Paul, Peter, Theophilus) do not hold as authors.
