Question 31. Why is He called “Christ,” that is, Anointed?

Answer. Because He is ordained of God the Father and anointed with the Holy Spirit[1] to be our chief Prophet and Teacher,[2] who has fully revealed to us the secret counsel and will of God concerning our redemption;[3] and our only High Priest,[4] who by the one sacrifice of His body, has redeemed us,[5] and ever lives to make intercession for us with the Father;[6] and our eternal King,[7] who governs us by His Word and Spirit, and defends and preserves us in the redemption obtained for us.[8]
