Light of Light, The Orthodox Truth
The Holy Spirit in Orthodox Theology
The Holy Spirit in The Orthodox Theology
is understood as the Third Person of the Holy Trinity — fully God, eternal, uncreated, worshipped and glorified together with the Father and the Son.
The Orthodox Church confesses in the Nicene-Constantinopolitan Creed:
“And in the Holy Spirit, the Lord, the Giver of Life, Who proceeds from the Father, Who together with the Father and the Son is worshipped and glorified…”
This teaching was defended especially by:
Saint Basil the Great ,
Saint Gregory the Theologian,
Saint Gregory of Nyssa and
Saint Athanasius the Great.
The Holy Spirit Is Fully God
The Orthodox Church rejects the ancient heresy of the Pneumatomachians (“fighters against the Spirit”), who claimed the Holy Spirit was a creature.
The Fathers taught that:
the Spirit sanctifies,
gives life,
reveals God,
dwells in the saints,
and performs divine actions.
Therefore He cannot be a created being.
Saint Basil writes that the Holy Spirit is:
inseparable from the Father and the Son,
sharing the same divine essence,
and worthy of the same worship.
The Spirit Proceeds from the Father.
One of the distinctive Orthodox teachings is that the Holy Spirit eternally proceeds from the Father alone.
Christ says in John 15:26:
“the Spirit of truth who proceeds from the Father…”
The Orthodox Church therefore rejects the later Western addition of the Filioque (“and the Son”) to the Creed.
The Father is understood as:
the sole source (arche) within the Trinity,
eternally begetting the Son,
and eternally causing the procession of the Holy Spirit.
This preserves the monarchy of the Father within Holy Spirit in the Life of the Church
In Orthodox spirituality, the Holy Spirit is not an abstract theological idea. The Spirit:
sanctifies the Church,
acts in the Mysteries (Sacraments),
illumines Scripture,
transforms the believer,
and leads humanity to theosis (union with God by grace).
The entire life of the Church is Pentecostal.
At every Divine Liturgy, the priest invokes the Holy Spirit in the Epiclesis: that the bread and wine may become the Body and Blood of Christ.
Pentecost
The feast of Pentecost is the great revelation of the Holy Spirit to the Church.
In Orthodox understanding:
Pentecost is not merely a past event,
but the continual life of the Church in the Spirit.
The descent of the Spirit upon the Apostles fulfilled Christ’s promise that the Comforter would come.
The Holy Spirit and Theosis
A central Orthodox teaching is that salvation is participation in the divine life by grace.
The Holy Spirit:
purifies,
illumines,
and deifies the believer.
As Saint Seraphim of Sarov famously taught:
“The true aim of the Christian life is the acquisition of the Holy Spirit.”
