Generally choosing to let their written opinions on various cases speak for themselves, most Supreme Court Justices tend to keep their thoughts on the issues facing America to themselves, but every once in a while, one of them will speak out and share their concerns.

Justice Samuel Alito, appointed to the high court in 2006 by former President George W. Bush, recently spoke at a gathering of Catholic judges and lawyers known as Advocati Christi in New Jersey and issued a stark warning about the threats facing religious liberty in this country, according to The Associated Press.

Citing his own dissent in the controversial 2015 Obergefell v Hodges Supreme Court ruling on same-sex marriage, Alito reminded listeners that opposition to the decision would be utilized to “vilify those who disagree, and treat them as bigots.”

“A wind is picking up that is hostile to those with traditional moral beliefs,” he said.

“We are likely to see pitched battles in courts and Congress, state legislatures and town halls,” Alito said. “But the most important fight is for the hearts and minds of our fellow Americans. It is up to all of us to evangelize our fellow Americans about the issue of religious freedom.”
