Almost any major religious story echoes across other religious groups. You can broaden the impact of your story with some additional reporting that places this all in a wider perspective. Don't assume you've spotted a religious trend, just because you've suddenly discovered it. Generally, most trends in religious life are really cycles. It's fairly easy to check the history and breadth of a trend.
Libraries are full of religious-studies books and resource materials.
Don't assume that a religious group's leadership truly speaks for its members. We know that Catholics often disobey the pope, many Baptists drink beer, etc. The same is true in non-Christian faiths and, in fact, it may be a crucial part of your story to explore the many ways American culture is reshaping traditional religions. It's almost impossible to make such statements. We're on safer ground when we attribute details to the specific group or person we're covering.
