Biblical Answer

The concept of 'theosis' in Eastern Orthodox theology is a vital aspect of understanding the nature of human beings. Theosis, or deification, refers to the process by which human beings become more like God through the indwelling of the Holy Spirit. This concept is rooted in the Orthodox understanding of the Trinity, where God is seen as a relational being who desires to share his life and nature with humanity. Theosis is not about humans becoming God or sharing in God's unique ontological nature, but rather about becoming partakers of the divine nature through union with Christ. This union is made possible through faith, repentance, and the sacraments.

Theosis is not a static state, but rather a dynamic process that continues throughout one's life. It involves a transformation of the human person, where the old self is put to death and a new self is born in Christ. This process is facilitated by the work of the Holy Spirit, who dwells within the believer and guides them towards spiritual growth and maturity. Theosis is not just about individual salvation, but also about the restoration of humanity to its original created state, where humans are able to live in harmony with God and with one another.

The concept of theosis has significant implications for our understanding of human nature. It suggests that humans are not just passive recipients of God's grace, but rather active participants in the process of becoming more like God. This understanding of human nature is rooted in the Orthodox concept of synergy, where humans and God cooperate together in the work of salvation. Theosis also highlights the importance of community and the role of the Church in facilitating the process of deification. Through the Church, humans are able to participate in the life of God and become partakers of the divine nature, which is the ultimate goal of human existence. In this sense, theosis is not just a theological concept, but a lived experience that shapes the way Orthodox Christians understand themselves and their place in the world.
