There is enough blame to go around on both sides.
Don’t really see what Archbishop Burke did wrong.
Seems to be a runaway parish board.
First they convert the parish hall to a bar and start serving beer, wine and hard liquor during Mass times. Both the pastor and the archbishop ask them to stop and they refuse.
Then they start grabbing all the collections and refuse to report their collections to the either the rest of the parish or the archdiocese. On several occasions, they refuse to allow an auditor review their finances as is required both by the archdiocese and Missouri law.
They refuse to meet with the archbishop on several occasions and refuse to state what their grievances with the archdiocese are. Without this, there is no way anyone can actually solve the problem as no one knows what it is.
At this point (2004), the Church board is interdicted.
Then they lock out the pastor and get a suspended priest from another diocese who does not have permission to leave his diocese, and has not been granted faculties by the archbishop to be their pastor.
Certain members of the board when to St. Louis county records and attempted (illegally) to change the deed for the parish property to add the names of individuals on the parish board, as well as the suspended priest.
After repeated warnings, the entire parish (or rather what few people remain) is placed under interdict.
Later the suspended priest participates in an unauthorized attempt to ordain women as priests.
After much individual counseling, the pastor and Church board are all excommunicated. The Vatican uphold the excommunications.
Two of the members of the board have reconciled with the archbishop and have returned to communion with the Church.
I do not see you basis to claim there is blame on both sides. From my perspective, as well as that of the Prosecuting Attorney of St. Louis County who is considering criminal charges against certain members of the parish board, I see nothing but fraud on the part of those few people on the parish board and that whacked-out suspended priest.
