Not a small amount of 21st century Christianity would be unrecognisable to the apostles or to The Church Fathers. Much of the expression of Christianity today is the church and the religion. But our inheritance in Christ is more simple and powerful than that.
It’s Christ as us. Jesus’ Message is a life more than a belief system. The core of the Kingdom Jesus began is the incarnation of the trinity in His people.
HEAVEN INVADES EARTH
Heaven comes to earth not just because we make a good moral stance or do some signs and wonders. Heaven comes to earth when we are the manifestation of God.
The Kingdom of God is communal and personal.
The trinity is a perichoretic communion of persons.
The nature of God is the nature of His drawing us into Himself.
We have a perichoretic relationship with God and through God with each other.
Such a relationship is realised in the Spirit and never in the law.
The incarnation brings heaven into the ordinary. God is as much with you and in you at the clothes line as He is in a praise and worship service.
The following takes some concentration but is worth thinking about.
BEING, PERSONHOOD AND COMMUNION
Thomas Torrance traverses this territory this way. “When the Church Fathers thought out the homoousial [Jesus one substance with God] and hypostatic interrelations [the distinctness of the three] of the three divine Persons within the one Being or Communion of the Holy Trinity, it became clear to them that the ontic relations [State of being] between the divine Persons belong to what they are as Persons.
LIVING PATTERN OF LIFE
No divine Person is who he is without essential relation to the other two, and yet each divine Person is other than and distinct from the other two. They are intrinsically interrelated not only through the fact that they have one Being in common so that each of them is in himself whole God, but also in virtue of their differentiating characteristics as Father, Son, or Holy Spirit which hypostatically intertwine with one another and belong constitutively to their indivisible unity within the Trinity.
There is an indivisible and continuous relation of being between the Father, the Son and the Holy Spirit so that the Being of the Godhead is understood to be whole or complete not in the Father only but in the Son and in the Holy Spirit as well. These ontic and holistic interrelations between the three divine Persons in virtue of which they are what and who they are as Persons are substantive relations.” (1)
We are talking union and communion – the opposite to separation and the complete undoing of the fall. This communion has reached out, the enterprise of the trinity that we call salvation and made us part of this communion – part of this perichoresis.
Alienated Adam and his race have been re-joined to the Family of God. This is what it means to be sons/daughters of God as a state of being in oneness as opposed to a figurative or notional oneness achieved by citing a proof text., doing a moral or keeping a law. Holiness, wholeness and real life is participating in God. He has drawn us into Himself.
