The Valley Family Forum sponsored the event and 500 people paid $50 each to hear the former chief justice Roy Moore.
In his speech, Moore argued that the federal government should not be involved in the way Americans express their religious beliefs.
"You know people say I'm proud that you illustrated your faith but guess what its also the law. It's the law of this country, its the very formation of our freedom," says Moore.
Moore defended his decision to acknowledge his faith and felt the government should not interfere with those wanting to publicly express their religious beliefs.
As former judge Moore was making his points inside, outside these protestors had a message of their own.
"We are out here standing up for the constitution principle of the separation of government and religion," says Eric Lefremiere, a protestor.
