The leader of Rhode Island's Roman Catholic Diocese has again entered the debate over gay marriage, calling it "immoral and unnecessary." Bishop Thomas Tobin released a statement Monday urging lawmakers to drop legislation to allow gay and lesbian couples to marry. Tobin says the Catholic Church rejects the "homosexual lifestyle" and says gay marriage poses a threat to religious freedom. Tobin also argues Rhode Island should wait for the U.S. Supreme Court to weigh in on the federal law defining marriage as being between a man and a woman. He says that if the state must consider gay marriage, it should be placed before voters as a referendum.
