'der Anhänger' and 'der Apostel' can both mean a person who supports an idea or doctrine. 'Anhänger' is more neutral and more general: an 'Anhänger' may simply agree with something or follow a group. 'Apostel' sounds stronger and more special. It means someone who spreads an idea with great zeal. In addition, 'Apostel' has an important religious meaning in Christianity. Learners may confuse the words because both have to do with conviction. In everyday language, 'Anhänger' is usually the safer choice. 'Apostel' fits better in religious texts or when someone advocates for something almost like a missionary.
