Question

About whose participation in the second missionary journey did Paul and Barnabas disagree?

Answer 1

Paul and Barnabas disagreed about John Mark's participation in the second missionary journey. Barnabas wanted to take John Mark with them, but Paul was opposed to it because John Mark had previously left them during their first journey, which caused a significant disagreement between the two. As a result, Paul and Barnabas parted ways; Barnabas took John Mark with him to Cyprus, while Paul chose Silas as his companion for the journey. This account is found in the Book of Acts, specifically Acts 15:36-40.
