Timothy was responsible for bringing order to their Sunday morning gatherings, which had become somewhat chaotic, unhealthy, and self-centered. Worship had become a barrier to growth rather than a means of growth. Paul's use of “everywhere” flows from his emphasis on all people in vv.1-7. If the gospel is for all people, then what all churches “everywhere” do on Sunday when they gather should not become a barrier for people to see and know Jesus. There may be specific applications for Timothy and for Christians in Ephesus, but there are general principles for all people in every church.
