If newcomers walk into a Protestant church on Sunday and hear an organ playing, and see hymnals, the odds are good that between 50 and 250 people will be in the pews.

If a church's attendance is larger than 250 -- especially if it's 1,000-plus -- visitors will usually see pop-rock "praise musicians" on stage, including a drummer. The hall will feature concert-level lighting and video screens displaying song lyrics. 

But here's a news flash from the front lines of what church leaders have, for several decades, called the "worship wars." According to a LifeWay Research survey, there's evidence of a "truce" between the "contemporary" and "traditional" worship forces. Then again, it's possible that church leaders have made up their minds and old debates inside many congregations have calmed down.

"We're not really talking about two enemies negotiating a cease fire," said Mike Harland, director of the LifeWay Worship team. "What I've seen happen in the 20 years that I've been part of this story is that the distance between the traditional and the contemporary churches has narrowed a bit. … People on each side of the divide have become more willing to compromise with the other."

This survey (.pdf here) was built on random telephone surveys of clergy in a variety of Protestant traditions during 2018, with the results weighted by church size and region, seeking balance.

A key finding was that only 15% of these American clergy said the biggest challenge they face linked to music and ministry was "navigating the varying preferences of members." A higher percentage (21%) said it was a bigger challenge to find vocalists and musicians to handle essential roles in worship.

When talking with individual pastors and worship leaders, Harland said he frequently hears them admit that their flocks simply don't contain members with the talents necessary to create a pop-rock band or "praise team" that can, week after week, perform contemporary Christian music at semi-professional levels. Thus, in many Protestant settings, individual talents -- not church tradition -- help shape a local congregation's worship "style."

Many pastors voice variations on this theme, he said. "We would love to sing all those new songs, but we don't have anyone who is talented on guitar and we don't have a drummer."

There is no question that, in addition to denominational worship traditions, some musical "style" questions are linked to church size.
