The fact that Pentecostalism has two founders—one white (Charles Parham), one black (William Seymour)—did not go unnoticed. It perfectly signified the interracial cooperation of the movement's early days, both at Azusa Street and in the new denominations. Not only did blacks and whites worship together with other races and ethnic groups, but many racists were transformed and prejudices were challenged.

Sadly, Parham's bigoted tendencies were not among these. He caricatured Seymour's "disgusting" Azusa Street revivals as "Southern darkey camp meetings." The short-lived relationship between Seymour and Parham foreshadowed the inability of Pentecostalism to maintain the racial harmony for very long. What emerged from the failed experiment, however, was a distinct movement. Neither that movement, black Pentecostalism, nor the larger movement, Pentecostalism, can be understood without knowing the early relationships between black and white Pentecostals.Go to whole article:
