The early Christian apologist Athenagoras may not be as famous as some of the other Church fathers, but he's a great example of someone who started out as an apologist against Christianity, but when he actually learned what the apostles and the Church taught, he was converted. He teaches us about the doctrines of the Trinity, and the Resurrection.
