Many Christians take for granted that their Sunday morning worship service is rooted in the New Testament, but why does the church in the New Testament seem very different from our own expressions of corporate worship? Frank Viola and George Barna come to the startling conclusion that most of what Christians do in church is rooted more in pagan culture than in the New Testament. Discover how many church customs really originated. This thought-provoking exploration into the background of how believers have worshiped for centuries uncovers many non-Christian roots. From the order of worship to the pastor's sermon, traditional dress codes to Christian education, Viola and Barna take a revealing look at Sunday morning. 304 pages, hardcover from Barna Books.
