Worship styles vary widely. The style is often determined by the generations within your church. One thing is for sure…it needs to serve the congregation and those you are trying to reach.
I’ve worked with churches wherein they are using older hymnals, some from very old hymnals I’ve never seen before. The familiarity can foster warm feelings from the past and make worship easier since they are memorized, however younger generations don’t listen to older style hymns. If your church is seeking to draw in a younger crowd, you probably need to work in modern, contemporary music. Generations from the 8Os on back grew listening to one style on the radio while in church sang a different style. Today, younger generations are listening to and desiring to sing the sang songs they hear on the radio, which is great!
