Pew Research Center analyzed online sermons in U.S. searches, taking a closer look at what people typically hear across religions:
For instance, the distinctive words (or sequences of words) that often appear in sermons delivered at historically black Protestant congregations include “powerful hand” and “hallelujah … come.” The latter phrase (which appears online in actual sentences such as “Hallelujah! Come on … let your praises loose!”) appeared in some form in the sermons of 22% of all historically black Protestant churches across the study period. And these congregations were eight times more likely than others to hear that phrase or a close variant. Although the word “hallelujah” is by no means unique to historically black Protestant services, this analysis indicates that it is a hallmark of black Protestant churches.
