Lincoln was shot on Good Friday. If only he had gone to church instead to the theater to watch a comedy... You know he was an atheist? His law partner (Herndon) made it clear that Lincoln didn't believe in religion.
When he went to church, it was just for show.
He was a deist like Thomas Jefferson or Thomas Paine, at least in his younger years. He wrote an essay expounding his beliefs and showed it to a friend, who threw it into the fire, warning him of the fatal consequences to his career if that had been published.
During the war he starts talking about Providence. How much of that he actually believed, I don't know.
Politicians just going to church for show? Who could imagine that?
