===Threefold office===
{{Main|Threefold office}}

The [[threefold office]] (Latin {{lang|la|munus triplex}}) of Jesus Christ is a [[Christianity|Christian]] doctrine based upon the teachings of the Old Testament. It was described by [[Eusebius]] and more fully developed by [[John Calvin]]. It states that Jesus [[Christ]] performed three functions (or "offices") in his earthly ministry – those of [[prophet]], [[priest]], and [[kingly office of Christ|king]]. In the Old Testament, the appointment of someone to any of these three positions could be indicated by anointing him or her by pouring oil over the head. Thus, the term ''messiah'', meaning "anointed one", is associated with the concept of the threefold office. While the office of king is that most frequently associated with the Messiah, the role of Jesus as priest is also prominent in the New Testament, being most fully explained in chapters 7 to 10 of the [[Book of Hebrews]].
