Bruce, F.F. The Book of Acts Revised. Grand Rapids: Eerdmans, 1988. Kindle Electronic Edition. “V. Paul Leaves Antioch and Moves to the Aegean World (15:36-19:20).” “A. Recently Planted Churches Revisited (15:36-16:5)” pp. 301-305.
In Acts 15:36-41 Paul and Barnabas have a dispute which results in their separation from one another. Bruce notes that even though it was an unpleasant situation Luke is very fair to both sides (Bruce 1988, 301). Paul did not trust John Mark as a companion, but Barnabas did. The disagreement resulted in Paul and Barnabas going in different directions, spreading the Gospel. Silas, formerly a leading figure in the Jerusalem church, accompanied Paul.
In the opening verses of Acts 16, Paul and Silas are joined by Timothy, who was from the area of lystra, in South Galatia (Bruce 1988, 303). Because of Timothy’s mixed parentage, to keep peace in the synagogues, Timothy was circumcised (Bruce 1988, 304). The encouragement of Christians continues as Paul, Silas, and Timothy bring the report of the Jerusalem council to the people.
