By David Carlin, The Catholic Thing - The religion of nationalism, however, unlike the religion of Communism, didn’t necessarily see itself as the enemy of Christianity. In some countries it imagined that it could co-exist with the old faith and that the two – nationalism and Christianity – could, so to speak, marry one another, or at least cohabit, locked in a not-quite-licit embrace. In the United States, for instance, being a good Christian made you a better American nationalist, and being an American nationalist made you a better Christian. Or so at least it has been widely felt.
