The root meaning of the term evangelion [gospel] would today best be translated "revolution." Originally it is not a religious or a personal term at all, but a secular one: "good news." But evangelion is not just any welcome piece of information, it is news which impinges upon the fate of the community. "Good news" is the report brought by a runner to a Greek city, that a distant battle has been won, preserving their freedom; or that a son has been born to the king, assuring a generation of political stability. "Gospel" is good news having seriously to do with the people's welfare.... whatever it is that God is about to do, it will be good news for the poor, bad news for the proud and the rich; it will be change, including changed economic and social relations.
