Good morning, John.

Some more perspectives.

I like how the Heidelberg Catechism, in similar manner to the Westminster Shorter, applies the terms first to Christ:

Quote
Question 31.
Why is he called CHRIST, that is, the ANOINTED ONE?
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 Fathere 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.

but then goes on to describe their outworking in the life of the Christian as well:

Quote
Question 32.
But why are you called a Christian?
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 to rule with him in eternity over all creatures.


Then there's the wonderful little suite in the Westminster Catechism for Young Children, which also draws attention to our need:

Quote

A. Christ has three offices.

Q. 65. What are they?
A. The offices of a prophet, of a priest, and of a king.

Q. 66. How is Christ a prophet?
A. Because he teaches us the will of God.

Q. 67. How is Christ a priest?
A. Because he died for our sins and pleads with God for us.

Q. 68. How is Christ a king?
A. Because he rules over us and defends us.

Q. 69. Why do you need Christ as a prophet?
A. Because I am ignorant.

Q. 70. Why do you need Christ as a priest?
A. Because I am guilty.

Q. 71. Why do you need Christ as a king?
A. Because I am weak and helpless.

In Christ,
Paul S
