Why is he called "Christ," meaning "anointed"?

Because he has been ordained by God the Father and has been anointed with the Holy Spirit¹ to be our chief prophet and teacher² who fully reveals to us the secret counsel and will of God concerning our deliverance;³ our only high priest⁴ who has delivered us by the one sacrifice of his body,⁵ and who continually pleads our cause with the Father;⁶ and our eternal king⁷ who governs us by his Word and Spirit, and who guards us and keeps us in the freedom he has won for us.⁸
