God, With, Us: Incarnation in Three Soundbites

I. Incarnation in Three Soundbites
1. Humanity without compromise
2. Divinity without compromise
3. Unity (or personhood) without compromise
Heresies = compromises

II. Humanity
Taken for granted in the New Testament
Theological conclusions from Jesus' humanity:
1. Romans 5:12-21: Jesus can reverse sin
2. 1 Corinthians 15: We can rise again
3. Hebrews 2:14-18, 4:15-16, etc.: Jesus can intercede

III. Divinity
Subtle in the New Testament
Just OK: "Prooftexts" (biblical one-liners)
John 20:28, Rom. 9:5, Heb. 1:8, 1 John 5:20, Titus 2:13 + 2 Peter 1:1, John 1:1, John 1:18, John 8:58
 
Better: Roles and acts of Jesus (narratives)
A role in creation: 1 Cor. 8:6, Col. 1:16, Heb. 1:2, John 1:2-3
Sovereignty over creation:
Calming the storm, walking on water, feeding miracles
Forgiving / judging: Healing the paralytic, sheep / goats, 2 Cor. 5:10
Central role in salvation: Luke 19:10, "savior" title, healings/exorcisms
Special relationship with the One who sent him:
Baptism, transfiguration, Matt. 11:27
Special relationship with the Holy Spirit:
John 14:26, John 15:26, John 20:21-23, Acts 2:33, 38
Always part of the NT's "trinitarian" triads: Matt. 28:19, 2 Cor. 13:14
 
Best: A common worship practice (liturgies)
"Lord" (kurios): 1 Cor. 16:22, Phil. 2:5-11 (after Isa. 45:22-23)
 
Humanity and divinity affirmed: Nicea, 325 and Constantinople, 381
 
IV. Unity
How are they one? Two schools of thought on "hypostatic union":
1. Alexandria: "Word-flesh" Christology (cf. John 1)
(Dangers: Compromises Jesus' true humanity)
2. Antioch: "Word-man" Christology (cf. Mark 1)
(Dangers: Compromises Jesus' unity and even divinity)
Chalcedon's uncompromising compromise, 451:
In Christ divinity and humanity are "without confusion, change, division, or separation"
Communication of attributes (communicatio idiomata):
Each nature influences (without compromising) the other
Result: Divine humanity (Athanasius), human divinity (Barth)
Analogy: Red-hot iron (John of Damascus)
Concurrence of relations:
The relationships constituting divine personhood and human personhood concur in one person
Either way, incarnation grounds doctrines of salvation (e.g., Anselm)
