There are a number of issues here. One, this has been done before. In the 18th century it was common to prohibit bishops from control of parish property which lead to the necessity for parish trustees. A big problem with those laws and this proposed law is that it is only focussed on Catholics.
The other side of this is that in this situation it was a group of Catholics that wanted this legislation, not discriminating Protestants. I do not know if this group of Catholics actually thought that this bill would become law or if they were trying to send a message to the bishops of the United States. I think that that message is this: "Bishops and priests have too much control over church finances and we do not trust you. WE NEED FINANCIAL REFORM!" I think the bill, if passed into law, would have created a whole new set of problems, but I think the message is appropriate. And of course, financial reform is not possible without ecclesial reform.
Sex abuse, parish finances and misspending... Perhaps these crucifixions will lead us to a new Church.
A Faithful Catholic
