I think that there are several religious aspects to the Montgomery Bus Boycott. The most elemental of which resides in the fact that it was church leaders in Montgomery that saw the opportunity to protest as part of the moral and ethical duty. The ministers understood that their role as community leaders and spiritual advisors compelled them to act and undertake the boycott. In this case, power comes from religious leaders, inspired by the political injustice experienced as a test of their faith. At the same time, the actual boycott itself reflected an exercise in Christian faith in that it did not advocate violence, but did advocate standing up to the evil of segregation. In true Christian manner, there was defiance against injustice, but a "turning of the cheek" in the refrain from violent confrontation. At the same time, the mass organization and collectivization of power that was seen in support of the boycott is reflective of how Christian notions of voice lead to social cohesion. The teachings of Jesus as one in which people respond as a group to the nature of injustice is something that is integral to the social philosophy of Christianity and also present in the Montgomery Bus Boycott.
Thanks, really helped :)
