Creed, Code & Cult
Creed - The creed is a set of beliefs a religion's followers are taught to believe. These can be about God, money, lifestyle e.t.c. but it is something a religion all believes in. E.g. Jesus died on the cross for Christianity and that there is only one God, Allah, and his prophet is Muhammed (pbuh) for Islam.
Code - A code is a set of rules such as the Ten Commandments of Christianity or the Five Pillars of Islam that followers must live by. These influence how the followers live.
Cult - The cult is the way the followers of a religion worship their God. This may include praying five times a day facing mecca (Islam) and a Bar Mitzvah (Judaism)
