Sounds to me that it is more polictical, that those in power did things that should not have done as it appears to me that diologue went out the window. it also appears to me that very stong egos were at play in that they wanted to push their own inflated weight around and try and force their own beliefs on the other. From what I have read in history it does not appears or seems to me that the Pope authorized anyone to perscute anyone whether in te east or in Bulgaria. That any of it was done it was done by those who thought that they had the power to do so. That does not mean that the Pope or the Catholic at large authorized it. There are big egos on both side of the issues that caused the schism. But thats what happens when each side refuses to listen to the other.
