Chapter Contents:
I. Question 35: The Meaning of Christ's Conception and Birth
A. Defining the Miraculous Conception This section refutes the Eutychian heresy that Christ's flesh was derived from the Holy Spirit, explaining instead that the Holy Spirit acted as the efficient cause, empowering the virgin birth. It clarifies that scriptural language about Christ being "born of God" or "the seed of Abraham" uses figurative language to describe lineage and divine action, not material origin.
B. Three Key Aspects of Christ's Conception by the Holy Spirit
Miraculous Formation: Christ was conceived in Mary's womb without male intervention, a unique event directly orchestrated by the Holy Spirit. This contrasts with ordinary human conception.
Sanctification in the Womb: The Holy Spirit purified Christ’s human nature in the womb, preventing original sin from tainting him. This was necessary for him to be a pure sacrifice, sanctify others, and guarantee the truthfulness of his words.
Hypostatic Union: The Holy Spirit united the divine and human natures in Christ at the moment of conception, forming a single person.
C. Significance of Christ's Birth from the Virgin Mary
Confirmation of True Humanity: Christ’s birth from Mary affirms his genuine human nature, derived from her substance.
Lineage and Fulfillment of Prophecy: His birth from Mary, a descendant of David, fulfills Old Testament prophecies about the Messiah's lineage and virgin birth.
Sanctification and Purity: His birth from a virgin signifies his sinless nature, sanctified in the womb.
Analogy to Spiritual Regeneration: Christ’s supernatural birth serves as a model for the spiritual rebirth of believers, which is a work of God, not human effort.
II. Question 36: Benefits of Christ's Holy Conception and Birth
A. The Mediator and Our Justification Christ's holy conception and birth establish him as our mediator. His sinless nature, united with the divine, allows him to cover our sin in God’s sight and reconcile us to the Father.
B. The Significance of Believing in Jesus Christ
Affirmation of Christ's Two Natures: Believing in Jesus Christ means acknowledging his true humanity and divinity, united in one person without confusion or separation.
Redemption and Sanctification: His miraculous conception and birth enabled him to redeem and sanctify us, granting us the right to become children of God.
III. The Two Natures in Christ
A. Proof of Christ’s True Human Nature This section counters heresies denying Christ’s full humanity, arguing that he possessed a body and soul like ours, except for sin. Evidence is drawn from:
Scriptural Testimony: Passages describing Christ’s physical experiences, emotions, and kinship with humanity confirm his human nature.
Divine Promises and Prophecies: Prophecies about the Messiah's human lineage and birth point to his true humanity.
The Office of Mediator: To atone for human sin, the mediator had to share the same nature that sinned.
B. The Unity of Christ’s Two Natures This section refutes the idea of two separate persons in Christ, arguing for one person with two distinct natures. This is because:
One Mediator: The role of mediator required a single person to both merit and apply salvation.
The Nature of Personhood: While Christ possesses two complete natures, only the Word subsists independently as a person. His human nature exists only in union with the Word.
C. The Hypostatic Union The two natures of Christ are united in one person by the Holy Spirit's work at conception. This union, termed "hypostatic" or "personal," maintains the distinct properties of each nature without confusion, change, division, or separation.
D. Necessity of the Hypostatic Union The union of Christ's divine and human natures was necessary for:
Redemption: Only a person who was both God and man could perfectly atone for human sin and merit our salvation.
Reconciliation: The unity of the two natures bridges the gap between God and humanity, allowing for reconciliation.
Mediation: This union enables Christ to represent both God to humanity and humanity to God, serving as our perfect mediator.
What are the key arguments for and against the two natures of Christ?
Arguments in Support of Two Natures in Christ
Scriptural Evidence: The source cites numerous scriptural passages supporting the dual nature of Christ. Hebrews 2:11-18 and 4:15 state that Jesus shared in human flesh and blood, making him relatable to humans in all things except sin. After his resurrection, Jesus encourages his disciples to touch him, confirming his physical body. The source emphasizes that these verses establish Christ as a true and natural man with a body and soul.
Fulfillment of Prophecies and Promises: The source highlights Old Testament prophecies and promises that foretold the Messiah's lineage, including being the seed of Abraham and the son of David. These prophecies solidify the argument for Jesus's true human nature as he fulfilled these predictions.
Necessity for Redemption: The source posits that the role of mediator necessitates Christ having a true human nature. Since humanity sinned, it logically follows that the same human nature must atone for those sins. A nature created out of nothing or brought from heaven would not suffice. Additionally, Christ's role as mediator extends into eternity, requiring him to retain his human nature forever, providing comfort to believers as their brother.
Union of Natures Enables Mediation: The source underscores the essential point that both natures, divine and human, must coexist within Christ for him to be an effective mediator. Had these natures not been united in the person of the Word, the work of redemption would have remained incomplete.
Arguments Against Two Natures in Christ
The Eutychian Heresy: The source discusses the Eutychian argument that Christ's conception by the Holy Spirit implies his flesh originated from the divine substance, resulting in the divine nature transforming into the human. The source refutes this by clarifying that phrases like "by," "from," or "of the Holy Spirit" signify an efficient cause, not a material one. It argues that the Holy Spirit empowered the conception, similar to how God's act of creation makes us born of God.
Apollinarianism: This heresy, as described by the source, maintained that Christ possessed a genuine human nature but with the Word replacing the human soul. The source counters this claim by using Christ's own words, "My soul is exceeding sorrowful, even unto death," demonstrating a distinct human soul capable of experiencing grief.
Schwenckfelder Doctrine: The Schwenckfelders' belief that Christ was human in name only is addressed. However, the source does not elaborate on specific arguments used by this group to support their stance.
The source mainly focuses on presenting a robust defense of the two natures of Christ, leveraging scriptural evidence, logical reasoning, and addressing opposing viewpoints to solidify its position.
How does the doctrine of the hypostatic union address the concerns of ancient and modern heresies?
The doctrine of the hypostatic union, which describes the union of Christ's divine and human natures in one person, is a key concept in Christian theology. This doctrine helps to refute various ancient and modern heresies that misrepresent the nature of Christ. Here's how:
Eutychianism: This ancient heresy argued that Christ's human nature was absorbed by his divine nature, effectively making him a divine-human hybrid. The sources explain that the Eutychians misunderstood the role of the Holy Spirit in Christ's conception. They interpreted phrases like "conceived by the Holy Spirit" to mean that Christ's flesh originated from the substance of the Holy Spirit. However, the sources clarify that the Holy Spirit acted as an efficient cause, enabling the conception but not providing the material substance of Christ's flesh. This distinction safeguards the distinctness of Christ's two natures while affirming the miraculous nature of his conception.
Schwenkfelderism: This modern heresy denies the true humanity of Christ, claiming he was only human in name. The sources counter this by providing scriptural evidence that affirms the reality of Christ's human body and soul. They cite passages where Christ refers to his own soul and experiences human emotions like sorrow. Additionally, they highlight prophecies that predicted the Messiah's descent from human lineages like Abraham and David, implying a true human nature. The sources emphasize that the role of mediator required Christ to possess a genuine human nature that could suffer and atone for human sin.
Apollinarianism: This ancient heresy proposed that the divine Word replaced Christ's human soul. This notion is refuted by the sources, which point to instances where Christ displays distinct human emotions and experiences, such as commending his spirit to God the Father upon death. These actions cannot be attributed to the divine Word and necessitate the existence of a separate human soul.
Docetism: While not explicitly mentioned, the doctrine of the hypostatic union also addresses the concerns of Docetism. This heresy claimed that Christ only appeared to have a human body, but it was not real. The sources repeatedly emphasize the reality of Christ's human nature:
Christ was born of the Virgin Mary, signifying the truth of his human nature derived from his mother's substance.
Christ's birth fulfilled prophecies that foretold a miraculous conception from a virgin of David's lineage.
The hypostatic union safeguards the completeness of both Christ's divine and human natures, ensuring they are "whole and distinct" while united in one person.
The doctrine of the hypostatic union, as explained in the sources, protects the integrity of both Christ's divinity and humanity. This understanding helps to refute various heresies by upholding the biblical portrayal of Christ as truly God and truly man, united in one person for the salvation of humanity.
