This is from my favourite of the 16th-century confessional documents, the Heidelberg Catechism:
Q. Why is he called "Christ," meaning "anointed"?
A. Because he has been ordained by God the Father and has been anointed with the Holy Spirit to be our chief prophet and teacher who perfectly reveals to us the secret counsel and will of God for our deliverance; our only high priest who has set us free by the one sacrifice of his body, and who continually pleads our cause with the Father; and our eternal king who governs us by his Word and Spirit, and who guards us and keeps us in the freedom he has won for us.
Q. But why are you called a Christian?
A. Because by faith I am a member of Christ and so I share in his anointing. I am anointed to confess his name, to present myself to him as a living sacrifice of thanks, to strive with a good conscience against sin and the devil in this life, and afterward to reign with Christ over all creation for all eternity.
