Sets of beliefs are a collection of ideas, values, and principles that guide an individual or group. Faiths, CREEDS, ISMS, CREDOS, and TENETS are all terms used to describe sets of beliefs. Faiths refer to a strong belief in a religion or spiritual practice. CREEDS are statements of faith that are shared by a religious group. ISMS are ideologies or philosophies that are based on a set of beliefs. CREDOS are similar to CREEDS, but they are more focused on moral beliefs. TENETS are principles or doctrines that are held to be true by a particular group.
