A person of censorious moral beliefs is often referred to as a PURITAN. The term 'PURITAN' originated in the 16th century and was used to describe members of the Church of England who wanted to purify the church of its Catholic influences. Puritans were known for their strict moral code and their belief in predestination, which held that one's fate was predetermined by God. They also believed in the importance of hard work and self-discipline.
