Two Hands, Contoured by Chalcedon (Handout)

Seeing the Two Natures of the Son in Our Perseverance from Keach’s Sermon on John 10:28

David A. Attebury

Text: John 10:27–30

“My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand. I and my Father are one.”

Driving question: Is it one hand or two hands?

Thesis: Benjamin Keach interprets the two hands of John 10:28–29 in the tradition of Chalcedonian categories: a Christian’s perseverance is founded upon the two distinct natures of Christ in one person. The hand of the Father is the Son himself (according to his divinity); the hand of the Son is his humanity and mediatorial office.

Keach’s Three Logical Moves

I.  The hand of the Father is his power and wisdom.

  • “Hand” as synecdoche for power (Isa. 9:1) and for God’s eternal purpose or counsel.
  • Assurance rests on divine immutability — God’s counsel cannot change because his nature cannot change.
  • Keach leans on Owen, Doctrine of the Saints’ Perseveranceaffectio, not passiones.

II.  The Son of God is the power and wisdom of God.

  • Christ “is called the Power of God, and the Wisdom of God” (1 Cor. 1:18).
  • All divine attributes are united and shine forth in the Son — unlike any single act of creation or judgment.
  • Eternal generation (ad intra) grounds his fitness to display God’s attributes in salvation (ad extra).

III.  Believers are in the hand of the Son according to both natures.

  • In the covenant of grace, the Son is Surety, Mediator, Sponsor (Heb. 7:22).
  • As God: wisdom itself, power itself, riches in glory to give.
  • As man: given wisdom, clothed with power, given the Spirit without measure.
  • Chalcedonian grammar on display: unconfused, immutable, indivisible, inseparable.

A Reformational Distinctive

One hand (proof of homoousios only): Augustine, Ambrose, Hilary, Lombard, Aquinas.

Two hands (divine nature and mediatorial humanity): Calvin, Keach.

Takeaway: The hand of the Father is the Son; the hand of the Son is his humanity. A Christian’s eternal security is uniquely accomplished by both of the Son’s natures, working in concert in one person — unconfusedly, immutably, indivisibly, and inseparably.
