c. 1200, "holy man;" early 13c., "a native or resident of Nazareth," childhood home of Jesus, from Late Latin Nazarenus, from Greek Nazarenos, from Hebrew Natzerath. As an adjective from late 13c. As "a follower of Jesus" from late 14c. In Talmudic Hebrew notzri, literally "of Nazareth," was used dismissively for "a Christian;" likewise Arabic Nasrani (plural Nasara). In Christian use, however, it can be a nickname for Jesus, or refer to an early Jewish Christian sect (1680s in English), or, in modern use, to a member of the Church of the Nazarene, a U.S.-based Protestant denomination (1898 in this sense).
1590s, "one who is characterized by strict adherence to method," from method + -ist. With a capital M-, it refers to the Protestant religious denomination founded 1729 at Oxford University by John and Charles Wesley. The name had been used at least since 1686 for various new methods of worship; it was applied to the Wesleys by their fellow-students at Oxford for their methodical habits in study and religious life. Johnson (1755) describes them as "One of a new kind of puritans lately arisen, so called from their profession to live by rules and in constant method." Related: Methodism.
