Mystery of Godliness

Introducing the section on the central figure in salvation, Pastor Martin begins a sub-series on the mystery of Christ's person by laying out why the doctrine is of supreme importance. He argues from Scripture that individual salvation depends on a right confession of who Christ is (John 20:31; John 8:24), the church is built upon a right confession (Matthew 16:13-18), the gospel cannot be maintained or proclaimed without a right view of Him (Romans 1:1-4), and this doctrine is the critical test of any professed work of the Spirit (1 John 4:1-3). He closes by pressing the personal question: Who is Jesus Christ to you?

Pastor Martin gives the simple statement of the biblical doctrine of Christ's person from the Shorter Catechism (truly God, truly man, two distinct natures united in one person forever), traces how the Athanasian Creed and Chalcedon articulated this confession in response to heresy, and then begins the biblical basis by expounding the first category of texts — those that explicitly designate Christ as God. He handles John 1:1, John 20:28, and Romans 9:5, pressing the conclusion that only one clear witness is needed to prove Christ's deity and calling hearers to fall with Thomas before their Lord and God.

Beginning the third great pillar of his Christology, that Jesus Christ is one person in two distinct natures forever, Pastor Martin offers a sober word of caution and exhortation before approaching the mystery itself. He urges three things: dependence on the Holy Spirit, determination not to fall short of or go beyond what is written, and patience with precise theological definition. He warns from Luke 24, Ephesians 4, and 2 Peter 3 that mental laziness about the person of Christ produces spiritual declension and unstable souls who will be tossed by every wind of doctrine.

Pastor Martin now sets out the biblical demonstration of Christ as one undivided person subsisting in two distinct, unmixed natures forever. Using a glove and hand analogy, and the witness of John 1, Philippians 2, Acts 20, Romans 1 and 9, and Colossians 2, he shows that the eternal Word became flesh without ceasing to be all that God is. He then shows from Christ's own consciousness and the apostolic witness that the natures remain distinct, with the one person speaking sometimes from the form of consciousness of his deity and sometimes from the form of his humanity, applying the doctrine to interpretation of Scripture, worship, and gospel proclamation.
