The Titles of Christ's Official Position in the Covenant of Grace

1. Head

The representative of His children in the Covenant of Grace as Adam was representative of his children in the Covenant of Works

For as by one man's disobedience many were made sinners, so by the obedience of One shall many be made righteous.

- Romans 5:19

2. Mediator

The One standing between a holy God and the guilty sinners who are included in Him, in the Covenant of Grace

And to Jesus the Mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.

- Hebrews 12:24

3. Surety

The One who obligated Himself and guaranteed to pay the full price for the debts of His elect church

By so much was Jesus made a surety of a better testament.

- Hebrews 7:22

4. Minister

The servant of God serving in God's presence and performing all that is needed for the benefit of His people

Now of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens;

A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.

- Hebrews 8:1-2

5. Testator

The life-giving Savior, who grants rich benefits through His death to all that are included in Him in the Covenant of Grace.

For where a testament is, there must also of necessity be the death of the testator.

For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.

- Hebrews 9:16-17
