faith of our fathers

One of the books Ella picked out at the school library today is about James Madison, which prompted this conversation: 

Ella: James Madison was a president!

Lauren: President Hinckley was an old president. 

Me: Gordon B. Hinckley was the president of the Church, and James Madison was president of the United States.

Lauren: I knew that. 

Ella: But almost all the presidents believe in God, Mom. At least, I know the first ones did.
