Tillich explains the need for a courage of individualization, to be apart from the group. Sitting in a darkened movie theater allows one a strong sense of being alone and having a strong sense of one's personal values. But even though the film may be shared with an audience, this is not communion. Tillich explains that complementary to this courage to be apart, one must have the courage to be a part of humanity. The tension between being apart and a part is a dynamic of faith.
Church forces the issue of the courage to play one's part as a part of the body.
This has the imminent prospect of causing irritation, sarcasm, strife, injured feelings, frustration, even damage. But that's what makes it Church, the body, the need for communion, and why Church makes movies more exciting, but why movies, as passive entertainment, don't do much for our confronting our own and others' short comings in the active life of a congregation. And I know LaGard Smith liked that remark even though it was wrong. And this service seems longer than the entire Godfather saga.
