It’s not what you think. To quote the Phoenix Business Journal, Bishop Kicanas is advocating the law suit. The purpose? To put an end to an evil law:
The Roman Catholic bishop in Tucson says the Catholic Church should join lawsuits challenging the state’s controversial new immigration law.
Bishop Gerald F. Kicanas of the Roman Catholic Diocese of Tucson, said in a memo to parishioners Monday he is asking the U.S. Conference of Catholic Bishops to consider joining lawsuits against the Senate Bill 1070 Support our Law Enforcement and Safe Neighborhoods Act. Gov. Jan Brewer signed the measure into law Friday.
Previously, the Arizona Bishops formally asked the governor to veto the bill. This looks like a debate which will not be going away soon.
