Few things are as fundamental to the New Testament as the reality of communion (koinonia). It means a commonality, a sharing and participation in the same thing. It is this commonality or sharing that lies at the very heart of our salvation. This communion is described in Christ’s “high priestly prayer”:
I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me. And the glory which You gave Me I have given them, that they may be one just as We are one: I in them, and You in Me; that they may be made perfect in one, and that the world may know that You have sent Me, and have loved them as You have loved Me (John 17:20-23).
The unity for which Christ prays is no mere “quality” of our life in Christ – but is our life in Christ. That this unity (communion) is the very life of salvation is made clear in St. John’s first epistle:
This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have communion [koinonia] with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have communion [koinonia] with one another, and the blood of Jesus Christ His Son cleanses us from all sin (1 John 1:5-7).
Here our communion with God is described as a communion of light – though the nature of that light is made clear: God is light. St. John uses light to say that our communion is a true participation in God, in His very life.
This same saving participation in the life of God is presented in Christ’s discourse on the Eucharist:
Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed, and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him. As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me (John 6:53-57).
I have written before about the problem of many modern English translations in which koinonia is rendered “fellowship,” a very weak translation indeed. Our very life in Christ is trivialized by unwitting (I hope) translators into a noun used to describe church socials. It is a witness to how far removed many modern treatments of our saving relationship with Christ have become from the classic treatments of Orthodox tradition.
The compartmentalization of theology (ethics, soteriology, ecclesiology, pneumatology – and the list goes on) frequently results in a fragmented, disjointed account of the Christian life. When you view the massive tomes that comprise the average systematic theology it is a marvel that the New Testament manages to be so short.
A telling weakness of many “theologies” is their failure to give account for the most common aspects of our Christian life. Prayer is a very straightforward example. Many systematic presentations of theology have no treatment of prayer whatsoever, despite the fact that we are bidden to “pray without ceasing.” How is it that something so pervasive finds no place in a theological description?
It is just this kind of spiritual myopia that marks theology that has departed from the Tradition of the faith and set off on its own trail of creativity. Thus, much has been written on “predestination” (a word which occurs but a few times in all the New Testament) while prayer is relegated to lesser treatments in what amounts to a category of recreational reading.
The Tradition does not treat prayer in this manner. Prayer is so much at the heart of the teaching of the faith that it is stated: Lex orandi, lex credendi – “the law of praying is the law of believing.” This is far more than saying that liturgy preserves the most primitive and pure proclamations of the gospel (though this is true). It is also saying that prayer itself is a pure expression of the gospel.
This becomes particularly clear when prayer is understood to be communion [koinonia] with God. And it is not prayer alone of which this can be said: the whole of the Christian life – every sacrament of the Church – has as its foundation our saving participation in the life of God.
One of the best places to begin thinking about communion with God is to ask the question: “What is wrong with the human race?” What is it about us such that we need saving?
The answer to that question is perhaps the linchpin of Christian theology (at least what has been revealed to us). Among the most central of Orthodox Christian doctrines is that human beings have fallen out of communion with God – we have severed the bond of communion with which we were created and thus we are no longer in communion with the Lord and Giver of Life, we no longer have a share in His Divine Life, but instead have become partakers of death.
St. Athanasius describes this in his On the Incarnation of the Word:
For God had made man thus (that is, as an embodied spirit), and had willed that he should remain in incorruption. But men, having turned from the contemplation of God to evil of their own devising, had come inevitably under the law of death. Instead of remaining in the state in which God had created them, they were in process of becoming corrupted entirel
