Serbian Orthodox Church is famous for its strict rules. And while it
has its share of followers, many Serbs adhere to the Islamic faith. A
Belgrade quiz will tell you that a person who isn't a Muslim is regarded
as a heretic by the Church. Being found guilty of being a heretic may
cause you lots of problems in future. That is the reason why an
applicant must have his own documents to show his or her religion. If
you are one of the few who do not have your own spiritual documentation
you might want to think about this kind of an examination.
