"Lutherans and Catholics began to say that they have a right to equal protection before the law for their ethical teachings. They argued: "If a Quaker says, 'I cannot go to any war,' he is doing what his church tells him to do. If a Catholic says, 'I could go to a good war but not a bad one,' he is doing what his Church tells him to do. Why does the government make provision for the Mennonite who follows his church's teaching but not for the Catholic who does?” Logically, that is a valid argument, but it is not valid in American law."
