According to the sources provided, deification ( theosis ) is the central theme and ultimate goal of man’s spiritual journey described in the “Beloved.” It is not just a metaphor, but a real calling of man to direct participation in the divine life of the Holy Trinity.

Here are the key aspects of deification in the context of the spiritual path:

1. Deification as God’s eternal plan

God, as the “most perfect Perfection,” from the beginning of time, ordained the deification of man as his highest goal. Man was created as a “divine image,” endowed with the will to receive “the true grace of deification” through the keeping of the commandment. Even after the Fall, this plan remains in force: the Son of God became the Son of Man precisely in order to “make us, men, sons of God” by grace.

2. The Path to Deification: From Purification to Unity

Deification in “Dobrotolyubia” is seen as the final stage of a three-part spiritual path:

• Action (praxis): Purification from passions through fasting, abstinence, and keeping the commandments. Without purification of the heart, the “light of truth” cannot shine in a person.
• Contemplation (theoria): The enlightenment of the mind to know the nature of creation and Divine mysteries.
• Deification (theosis): Complete union with God, where a person becomes “a god by grace.” This is described in sources as a “priesthood of the mind,” where a person becomes a partaker of the divine nature.

3. The role of the Jesus Prayer and grace

The main tool on the path to deification is the condition of prayer (the constant invocation of the name of Jesus Christ in the heart).

• Through prayer, the mind is purified, enlightened, and becomes “luminous,” adhering to God as one spirit with Him.
• The grace received at baptism as the “divine family” is hidden under the passions, but through prayer it begins to shine, leading a person to perfection.

4. Deification as a real change in nature

Deification concerns the whole fullness of human nature—spirit, soul, and even body. When the mind is united with God, it is “changed by divine change,” becoming beginningless and infinite by the action of grace, although remaining created in essence. The deified person becomes an “earthly angel,” reflecting in himself the original beauty of God’s image.

5. Universality of purpose

Sources emphasize that deification is not the exclusive privilege of monks, but the universal calling of every Christian . Every person, regardless of their status, is called to find the “treasure hidden in the heart”—Christ—and through union with Him to attain unity within themselves and with the Creator.

Therefore, deification is the “royal road” that returns man to his true dignity, making him a partaker of eternal glory and divine love.
