Heidelberg Catechism – Lord’s Day 12
Q. Why is he called Christ, that is, the Anointed One?
A. Because he is ordained by God the Father and anointed with the Holy spirit to be our chief Prophet and Teacher, fully revealing to us the secret purpose and will of God concerning our redemption; to be our only High Priest, having redeemed us by the one sacrifice of his body and ever interceding for us with the Father; and to be our eternal King, governing us by his Word and Spirit, and defending and sustaining us in the redemption he has won for us.
Q. But why are you called a Christian?
A. Because through faith I share in Christ and thus in his anointing, so that I may confess his name, offer myself a living sacrifice of gratitude to him, and fight against sin and the devil with a free and good conscience throughout this life and hereafter rule with him in eternity over all creatures.
