If you look at the list previous is has more than a small hint of power politics. By denying access to the sacraments one can strike the fear of God into someone. But I don’t think God works like that. Philosophically speaking, He is unlikely to be all that keen on human political shenanigans. And if you read the bible it does not say piss off some powerful dude and you will go to hell. At least that is my reading of it. But woe betide anyone who upsets the tribal elders! Through the use of ritual magic, they will exclude and excommunicate you. They will draw up a spell, a legal document of exclusion and take away your privileges. In days gone by, they would even burn your ass. This phenomenon of exclusion is widespread. It can also be associated with ritual scapegoating as if that fully cleanses. We might exclude a sad randy film director from the academy and then breathe a sigh of relief, the endemic problem is obviously “sorted” by this ritual. “Look we have done something about it! Aren’t we good?”
Despite the mission statement of any organisation, when it comes down to it, it is so often about socio-political power and power structures. We may profess otherwise, but that is the bottom line, no matter how much we try to kid ourselves.
Whilst we seek socio-political power within that context we are susceptible to its levers. If we seek to climb the greasy pole, we must play along. If not and “it is my(our) way or the highway”. Under certain circumstances the open road looks a lot more inviting than the greasy pole.
This technique, this method of exclusion from the tribe, is ancient. No matter how much pomp and circumstance it is dressed in, it is primitive.
Excluding does not solve, it is like neglecting inconvenient data points in an experimental run. I am also unconvinced that it enhances the long-term tenability of the socio-political power base that does the exclusion. You can’t exclude everyone. It may have a short-term effect. It is not quite the same as creating a martyr but can have a similar, if reduced, outcome.
