Which of the following actions is NOT attributed to Peter's leadership in Acts?

The action of writing letters to churches is not attributed to Peter's leadership in the Book of Acts. While Peter is a prominent figure in Acts and engages in significant leadership through actions such as performing miracles and acting as a spokesman for the apostles, the letters to the churches, often referred to as epistles, are more commonly associated with the Apostle Paul and some other apostles, such as John and James.

In Acts, Peter focuses primarily on preaching, performing miracles, and making decisions that shape the early church. His role as a spokesman during key events showcases his leadership in guiding and teaching the followers of Christ. Contrastingly, while he does have epistles in the New Testament, the specific actions of writing letters are not highlighted in the narrative of Acts itself, making this particular option the correct choice.
