This is according to Catholic historian Henry Karlson , who on Monday wrote a warning to his fellow faithful in which he explained the contradiction of their Christian nationalism and worship of Trump. “I find it extremely disheartening to see many Christians either accept what Trump does, obeying him without question, or outright promoting his agenda,” writes Karlson. The problem with Christian nationalism is that it cannot truly be Christian; Christians can be a part of the movement, but they do so against the teachings of Christ.” “This is exactly what Trump wants from the people of the United States,” asserts Karlson. “He wants to be adored; he constantly promotes himself, putting his name and image on everything he can, trying to make sure everyone identifies the United States with him.
