See the bill. From the actual bill:
Statement of Purpose:
To revise the corporate governance provisions applicable to the Roman Catholic Church and provide for the investigation of the misappropriation of funds by religious corporations. (emphasis added)
See the (video, etc.) response of the Roman Catholic Diocese of Bridgeport.
The reasons for introducing the bill are obvious: kill a major entity against same-sex "marriage" and abortion. Also, it makes people consider the very un-Catholic idea that the Church is a democracy. The Church is not a democracy (unlike the Episcopal Church, Quakers, etc.): the (Arch)Bishop, accountable to Rome, is ultimately in charge. (The pope is ultimately answerable to the Holy Trinity.)
Pray for this country that has forgotten its Constitution (in so many ways) and ideas of the Founding Founders.
