One more example of how the Catholic Church is stuck trying to incorporate appropriate responses to "possession" claims (i.e., psychology) while not giving up fundamental beliefs (i.e., possession). As I've posted before, the Church's official position these days are that all other avenues (medical, psychological) should be exhausted before resorting to exorcism. (Of course, there's a lot of "cowboy" priests in the RCC that seem to do whatever they want until they're jerked up short.)
I give them credit for trying to find a compromise solution, but I think they could be doing a much better job of it. Realistically, though, the politics in the RCC are savage and pervasive and always have been - so it's no surprise to me that a conservative and literalist-leaning faction might be able to pull this off and force this kind of class to appear in the Vatican College.
