“It is no longer I who live, but it is Christ who lives in me”

“It is no longer I who live, but it is Christ who lives in me” is Paul’s concise description of a life transformed through Christ’s presence. In the book, the statement connects mystical experience to both theology and conduct: Albert Schweitzer reads it as the defining expression of Paul’s Christ-mysticism, and Bernard of Clairvaux invokes it to describe a changed allegiance from self-interest to service.

Paul's Christ-centered mysticism

Albert Schweitzer, the missionary doctor and author of The Mysticism of Paul the Apostle, treats Paul as a rich source for understanding Christian mysticism. Paul recounts hearing Jesus on the road to Damascus and describes an ascent to the third heaven and Paradise. Yet Schweitzer distinguishes these experiences from classical mysticism: Paul does not write of becoming one with God. Rather, Schweitzer argues, Paul has a Christ-mysticism, in which encounter with Christ brings a person into relationship with God. The statement about Christ living in him gives that account its most direct formulation.

Schweitzer makes the expression central to his assessment of Paul’s achievement. At the close of his book, he writes, “Paul’s greatest achievement was to grasp, as the thing essential to be a Christian, the experience of union with Christ.” The distinction matters: the phrase describes neither a report of mystical ascent nor an abstract claim that the individual disappears into God. It identifies the Christian life with Christ’s presence within the person, and Schweitzer presents that union as essential to being Christian.

Bernard's turn from self-interest

Bernard of Clairvaux gives the Pauline words a practical and communal force. In a sermon on the Song of Songs, he reflects on the complaint that one has not kept one's own vineyard. Bernard relates the image to his responsibilities at Clairvaux, where anxieties, disputes, and visitors could leave little time for prayer. He also interprets the neglected vineyard through the example of Peter and Paul, who set aside their own interests to care for others and were not afraid to die for the name of Jesus Christ.

Against that background, Bernard acknowledges that he once lived at a lower level, looking after his own interests, but now holds different values. His identification with Paul’s words marks this change: a life centered on the self yields to a life directed by Christ and service to others. The phrase therefore carries an ethical consequence. Its claim about inward transformation is tested in what a person is willing to relinquish and whom that person undertakes to serve.

Presence expressed in practice

The book places such inward transformation alongside modest, repeated practices rather than treating mystical life as a pursuit of spectacular experiences. On a visit to Gethsemani, a student asked a monk how to deepen prayer; the monk advised praying the Psalms. The author adopted that counsel as a steady practice. Elsewhere, the book describes the Society of Friends' emphasis on the Inner Light, silent worship, and attentiveness to the Holy Spirit. These examples are not presented as quotations or interpretations of Paul’s statement, but they show how an inward orientation toward God can take shape in prayer and attentive communal life.

Dorothy Day's account of service gives the idea another concrete setting. She believed that Christ was present in people in need, and that feeding or sheltering them was service to Christ. The work could be difficult: guests at Catholic Worker houses might be hostile or demanding, and Day insisted that practical love was harsher than love imagined at a distance. Her understanding of Christ among the poor resonates with the book’s wider insistence that spiritual life changes how people treat one another. Read beside Bernard’s use of Paul, the expression joins inward allegiance to outward responsibility.

A life formed over time

The book cautions against treating spiritual practice as a device for producing a single extraordinary experience. Prayer, meditation, study, and silence may feel dry on some days and rich on others; their importance lies in their cumulative effect over years. It recommends beginning simply, perhaps with a Psalm and the Lord’s Prayer, and developing a routine that helps a person become more receptive to God. Mystics, it observes, prayed the Psalms, kept silence, fasted, and valued worship with others; religion was not a leisure activity separated from the rest of life.

Within that account, Paul’s phrase names an orientation that is sustained through practice and made visible in conduct. It is not a formula for attaining mystical union by personal effort: the book presents relationship with God as a gift of love and mercy. Its paired emphases—Christ’s inward presence and a life directed beyond self-interest—allow the expression to serve at once as a statement about mystical experience and as a measure of transformed living.
