I certainly agree with Rick Warren that the culture in a geographical area of the nation should help determine a church's worship style. I do disagree with discontinuing the use of hymns in any worship service. At our church we use a blended worship style comprised of both choruses and hymns. The hymnody of our faith is essential for two reasons, it connects us to the historical church and it contains the doctrines of our faith. Hymns are timeless and for that reason they are always contemporary and can fit any culture.
