Kenosis
The Biblical Foundation
The concept of kenosis takes its name from the Greek verb kenoo, meaning "to empty," which appears in Philippians 2:7. In one of the most exalted passages of the New Testament, Paul describes the incarnation of Christ: "Though he was in the form of God, he did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross" (Philippians 2:6-8).
This passage, often called the "Christ Hymn" or Carmen Christi, is the primary text for understanding the kenosis. It describes a voluntary movement from glory to humility, from the form of God to the form of a servant, from heavenly exaltation to earthly obedience and death.
What Did Christ Empty Himself Of?
The central theological question is what the "emptying" involved. Paul's language is carefully chosen. He does not say Christ emptied Himself of something but that He emptied Himself by taking the form of a servant. The emptying was accomplished not by subtraction but by addition — the Son of God took on human nature without ceasing to be divine.
Historically, theologians have understood this in different ways. Some have argued that Christ set aside certain divine attributes, particularly omniscience and omnipotence, during His earthly life. Others maintain that He retained all divine attributes but voluntarily chose not to exercise them independently of the Father's will. Still others emphasize that the emptying was primarily a matter of outward glory and privilege — the eternal Son exchanged the visible splendor of heaven for the humble circumstances of human life.
The passage itself focuses on status and posture rather than metaphysical mechanics. Christ did not cling to the privileges of deity but freely embraced the condition of a servant. The movement is from self-assertion to self-giving, from privilege to sacrifice.
Evidence of Both Deity and Limitation
The Gospels present a portrait of Jesus that holds together extraordinary divine knowledge and genuine human limitation. Jesus knew people's thoughts (John 2:24-25), demonstrated authority over nature (Mark 4:39), forgave sins (Mark 2:5-7), and accepted worship (Matthew 14:33). These suggest undiminished deity.
Yet Jesus also grew in wisdom (Luke 2:52), experienced hunger and fatigue (Matthew 4:2; John 4:6), was genuinely tempted (Hebrews 4:15), learned obedience through suffering (Hebrews 5:8), and expressed amazement (Matthew 8:10; Mark 6:6). Most strikingly, He stated that He did not know the time of His return: "But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father" (Mark 13:32).
This last statement has been the most difficult for theologians. If the Son is truly God, how could He be ignorant of anything? Various explanations have been offered: that Jesus spoke from His human nature alone, that He voluntarily refrained from accessing certain knowledge, or that the incarnation involved a genuine self-limitation that remains mysterious.
Historical Theological Development
The early church councils addressed related questions without using the specific term "kenosis." The Council of Chalcedon (451) affirmed that Christ is one person with two natures — fully divine and fully human — "without confusion, without change, without division, without separation." This framework sets the boundaries within which kenosis must be understood: the emptying cannot mean the loss of deity, or the incarnation would be reduced to a mere human life.
Kenotic theology emerged as a distinct school of thought in the 19th century, particularly among German Lutheran theologians such as Gottfried Thomasius and Wolfgang Friedrich Gess. They proposed various theories about which divine attributes were surrendered during the incarnation. These ideas sparked intense debate, with critics arguing that a God who could cease to be fully God is no God at all.
More recent theologians have sought a middle path, emphasizing that the kenosis is fundamentally an act of love rather than a metaphysical transaction. The Son did not diminish His nature but expressed it most fully through self-giving love. As one theologian put it, the cross is not the contradiction of divine power but its supreme expression.
The Pattern for Believers
Paul's reason for introducing the kenosis in Philippians was not primarily doctrinal but practical. He urged the Philippians: "Have this mind among yourselves, which is yours in Christ Jesus" (Philippians 2:5). The self-emptying of Christ is presented as the model for Christian community — where believers set aside privilege, status, and self-interest for the sake of others.
This ethical dimension transforms kenosis from an abstract doctrine into a daily calling. Just as Christ did not consider equality with God something to be exploited for His own advantage, believers are called to look "not only to their own interests, but also to the interests of others" (Philippians 2:4). The downward movement of the incarnation — from glory to servanthood to death — becomes the pattern for authentic discipleship.
Biblical Context
The primary text is Philippians 2:5-11, Paul's Christ Hymn describing the incarnation. Supporting passages include Mark 13:32 (the Son's limited knowledge), Luke 2:52 (Jesus growing in wisdom), Hebrews 4:15 (genuine temptation), Hebrews 5:8 (learning obedience through suffering), John 1:1-14 (the Word becoming flesh), and 2 Corinthians 8:9 ('though he was rich, yet for your sake he became poor'). The Gospels consistently present both divine authority and human limitation in Jesus' life.
Theological Significance
Kenosis addresses the central mystery of Christian faith: how the infinite God became a finite human being without ceasing to be God. It affirms that the incarnation was not a disguise or pretense but a genuine entry into human experience. The doctrine protects both Christ's full deity and His full humanity, ensuring that His work of salvation is accomplished by one who is truly God and truly man. As an ethical model, kenosis defines Christian character as self-giving rather than self-promoting, establishing humility and sacrificial love as the marks of authentic discipleship.
Historical Background
Kenotic theology developed significantly in the 19th century among German Lutherans, though its roots trace to the church fathers who wrestled with the relationship between Christ's divine and human natures. The Council of Chalcedon (451) provided the orthodox framework: two natures in one person. Medieval theologians like Thomas Aquinas discussed Christ's human knowledge and its limitations. The Reformation brought renewed focus on Philippians 2 as both a Christological and ethical text. Modern kenotic theologians include P.T. Forsyth, who emphasized that kenosis was the supreme expression of divine love rather than the abandonment of divine power.
