The Doctrine of the Holy Trinity

The doctrine of the Holy Trinity is not merely an “article of faith” which men are called to “believe.” It is not simply a dogma which the Church requires its good members to “accept on faith.” Neither is the doctrine of the Holy Trinity the invention of scholars and academicians, the result of intellectual speculation and philosophical thinking.

The doctrine of the Holy Trinity arises from man’s deepest experiences with God. It comes from the genuine living knowledge of those who have come to know God in faith.

The paragraphs which follow are intended to show something of what God has revealed of Himself to the saints of the Church. To grasp the words and concepts of the doctrine of the Trinity is one thing; to know the Living Reality of God behind these words and concepts is something else. We must work and pray so that we might pass beyond every word and concept about God and to come to know Him for ourselves in our own living union with Him: “The Father through the Son in the Holy Spirit” (Eph 2: 18–22).

The Holy Trinity in Christian Life

The new commandment of Christian life is “to be perfect as your heavenly Father is perfect” (Mt 5.48). It is to love as Christ Himself has loved. “This is My commandment, that you love one another as I have loved you” (Jn 15.12). Men cannot live the Christian life of divine love in imitation of God’s perfection without the grace of the Holy Spirit. With the power of God, however, what is impossible to men becomes possible. “For with God all things are possible” (Mk 10.27).

The Christian life is the life of God accomplished in men by the Spirit of Christ. Men can live as Christ has lived, doing the things that He did and becoming sons of God in Him by the power of the Holy Spirit. Thus, once more, the Christian life is a Trinitarian life.

By the Holy Spirit given by God through Christ, men can share the life, the love, the truth, the freedom, the goodness, the holiness, the wisdom, the knowledge of God Himself. It is this conviction and experience which has caused the development in the Orthodox Church of the affirmation of the fact that the essence of Christianity is “the acquisition of the Holy Spirit” and the “deification” of man by the grace of God, the so-called theosis.

The saints of the Church are unanimous in their claim that Christian life is the participation in the life of the Blessed Trinity in the most genuine and realistic way. It is the life of men becoming divine. In the smallest aspects of everyday life Christians are called to live the life of God the Father, which is communicated to them by Christ, the Son of God, and made possible for them by the Holy Spirit who lives and acts within them.
