You only have to skim the surface of the anti-Catholic material available on the World Wide Web to realise that, though written 150 years ago, Newman's lectures unmasking the shallow intellectual foundations of anti-Catholicism are still highly relevant. This is no period piece, exactly the same calumnies are being pedalled today. Newman, like some current ex-Protestant converts to the Catholic Church, can pinpoint the double standards and shoddy arguments of his Protestant accusers because he was once a convinced Protestant himself.
