Catholic mystics such as St. John of the Cross and St. Teresa of Ávila are renowned for their deep interior spirituality and contemplative insights. Their writings, particularly those dealing with the soul’s union with God, frequently interpret the Genesis account through the lens of inner transformation and mystical progression. Within this framework, the Tree of Life and the Tree of the Knowledge of Good and Evil are often viewed symbolically, reflecting the inner dynamics of the soul’s journey toward—or away from—God.

For these mystics, the Tree of Life represents Christ, particularly as He is encountered in the Eucharist, and as the fulfillment of the soul’s longing for union with the divine. It is not merely a tree planted in Eden, but a symbol of the final stage of the mystical journey—the unitive state, in which the soul abides in deep communion with God through grace, love, and contemplation. This tree also points to spiritual nourishment, healing, and transformation, often mediated through sacramental life and contemplative prayer.

In contrast, the Tree of the Knowledge of Good and Evil symbolizes disordered self-reliance—specifically, the soul’s attempt to grasp truth or moral autonomy apart from God’s love. It represents pride, intellectualism detached from spiritual humility, and rationalism unmoored from divine revelation. In this view, the Fall is not simply an event in redemptive history, but a recurring inward reality: the soul’s turning inward on itself, seeking knowledge without love, control without trust, autonomy without dependence. Eden itself is often interpreted as a spiritual state—a condition of inner harmony with God rather than a geographical location.

The way back to the Tree of Life, according to this view, is through the threefold path of the mystical life: the purgative, illuminative, and unitive stages. These involve a gradual detachment from sin and self, increasing illumination through prayer and spiritual insight, and finally the soul’s loving union with God (2019). While these stages reflect a rich tradition of spiritual formation, the mystical reading of Genesis can obscure the clear biblical teaching about the nature of sin, the literal Fall, and the objective, once-for-all redemptive work of Jesus Christ.

The Trees Were Historical and Christ Is Our Way

While Catholic mysticism offers profound reflections on the soul’s relationship with God, its symbolic reading of the Genesis trees and the Fall introduces theological risks when it overshadows the historical and doctrinal clarity of Scripture. The Tree of Life and the Tree of the Knowledge of Good and Evil were real trees with real consequences, not merely symbols of inner states or metaphysical realities.

These trees were part of a historical creation, planted in a real garden for a theological purpose. The Tree of Life was God’s provision for sustaining eternal life, and the Tree of the Knowledge of Good and Evil was a moral boundary—a test of obedience. The issue was not that Adam and Eve turned inward in contemplation, but that they willfully disobeyed God’s direct command: “But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die” (Genesis 2:17).

The Fall is not best understood as an allegory of inward spiritual failure or gradual separation from grace, but as a real event in history. Paul confirms this in Romans 5:12: “Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.” This historical fall brought spiritual and physical death—not just a loss of contemplative harmony, but real separation from God. The solution is not a mystical process of ascent, but redemption through Christ alone.

The mystical model of purgation, illumination, and union can subtly imply that salvation is a process completed through human effort, prayer, and spiritual advancement. But the Gospel proclaims that salvation is a gift—not the result of spiritual progression, but the fruit of Christ’s finished work. Ephesians 2:8–9 teaches: “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”

Christ does not merely stand at the top of the mountain to welcome those who climb through stages of inner perfection. He came down the mountain, bore our sin on the cross, and opened the way back to the Tree of Life through His blood.

Conclusion: The Path to the Tree of Life Is Not Mystical Ascent, but Gracious Redemption

Catholic mystics like St. John of the Cross and St. Teresa of Ávila offer profound meditations on the love of God and the soul’s longing for Him. However, their symbolic interpretation of Genesis—especially the meaning of the two trees—can diminish the gravity of the historical Fall and the sufficiency of Christ’s redemptive work.

The Tree of Life is not the reward of mystical union, but the gracious promise of eternal life through Jesus Christ (Revelation 2:7). The Tree of the Knowledge of Good and Evil is not simply a symbol of spiritual self-reliance, but a reminder of the cost of disobedience and the necessity of submission to God’s Word.

We do not ascend back to Eden through spiritual stages; we are brought back by the pierced Savior, who said: “I am the way, the truth, and the life: no man cometh unto the Father, but by me” (John 14:6).
