The Eastern Christian weltanschauung, as our Brother Vico put it, is all about Theosis and how this impacts our daily life.
The Eastern Christian worldview focuses on the Holy Trinity, the Father and the Son and the Holy Spirit. There is a Trinitarian perspective to God that is emphasized like no where else. Prayers in the East end in the Name of the Holy Trinity. As Fr. Jungmann once wrote, the East has a “social conception of the Deity.”
Christ’s Divine Incarnation, for the East, is also an emphasis on Divinity. Divinity does not demean our humanity, but transfigures and transforms it. In my Latin Catholic high school, my priest-teachers would often “jab” at the Eastern Churches for their “overemphasis” on Christ’s Divinity.
But this is not an emphasis on His Divinity - but on the Divinization of His Humanity and through Him, our Divinization.
We are meant to be deified by partaking in the Body of Christ through the Holy Spirit. The goal of the Christian life is the “acquisition of the Holy Spirit” the Third Divine Person. We have, in fact, a special relationship to each of the Three Divine Persons who are equally glorified and adored by us.
The deifying role of the Holy Spirit is everywhere prevalent in the Eastern Church. The iconography speak to Theosis/Divinization, indeed, all of the Cosmos is transformed through the Divine Son of God, our Lord, God and Saviour, Jesus Christ.
And this Theosis is a dynamic process - it never ends, not on earth, not even in heaven.
This is why we are called to ceaseless prayer in the Name of the Holy Trinity and in that of Jesus Christ, to frequent Communion of the Most Precious and Most Holy Body and Blood of OLGS Jesus Christ. Everything in our spiritual life is geared toward our Divinization/Theosis in Christ through the Holy Spirit, toward the transformation of those around us, our society, nation, the world in Christ.
For the East, the emphasis is not that Christ “humbled Himself to share in our humanity,” but that He raised us up through His Cross, Resurrection and His Holy Spirit.
The Most Holy Mother of God and the Angels and Saints are the heavenly, deified Communion of the Saints that are continually deified in the Lord and who pray for us, that we might have an ever-abundance of Communion with Christ and acquire the Holy Spirit more and more.
The focus in the West, even with Vatican II, was to bring the Church “into the modern era” and to assess modern society in more positive terms.
That is completely outside the scope of the Eastern Christian worldview. It is the modern world that needs the divinizing Presence of Christ and His Holy Spirit. Without this, the modern world is limited by its pride in its technological achievements which it imagines makes God somehow irrelevant.
The modern world needs to see the world through spiritual eyes in the first instance - it is not for the Church to adapt itself to a world that is grounded in sense-based realities only.
This is what the Christian East holds out to the entire world. The mission of the Christian East is a universal one.
