For many years I had a ”continuation theology” which saw the church as the continuation of Israel and therefore receiving all the covenant promises and benefits. This was partly a reaction to the dispensationalism I was first taught and was encouraged by my reading of the reformers and English Puritans.
Now my thoughts have been changed somewhat though I do believe we are the true “Israel of God”. Since the magisterial reformers and Puritans all envisioned “National churches” where the membership of church and state was coterminous (with every child baptised and an overlap between social and ecclesiastical discipline) it seemed reasonable to emphasise that somehow every Christian nation/church was in a covenant with God analogous to and growing out of Israel’s national covenant with God.
Most Presbyterian and Anglican covenant theology was forged in that thought-world. I doubt whether the reality was ever close to the theory – think of Luther’s unsatisfactory fudge of “ecclesiola in ecclesiam” which was an attempt to recognize a sort of two tier level of fellowship. In any case I am certain that species of covenant continuation is untenable now. As I have explained previously, I believe many of the covenant promises and privileges of Israel have now been thrown open to the whole world in the Gospel of Christ.
I believe furthermore that Christ has in himself fulfilled the covenant obligations which Israel failed in and that both common and special Grace flow from the covenant sworn between Father and Son and sealed at the cross.
So what is the basis of Christian community if it is not covenant? The answer is, I believe, simple and written all over the pages of the bible; it is kinship. The tie of kinship is obvious in the Law of Moses – how often is one’s obligation described as to “your brother” or your “fellow Israelite” or some other such term? Every Israelite was a blood relative.
My relationship with other believers is not one of a colleague nor of a covenant commitment to them. We are brothers (in Christ). This is the fellowship (commonality) of the Holy Spirit. The term “New Covenant Community” is too plastic for me – it can be shaped in too many ways. But if you and I have been made by the grace of the Spirit into members of the “household of God” my obligations are clear and far-reaching. It makes the Sovereign God Himself the centre of the church. We are the assembly of the Christ, the community of the Spirit, the children of the Father.
Incidentally, I am a little uncomfortable with making the leadership into a major focus of community. Sometimes fellowship exists in spite of leaders rather than because of them. I do not believe the stars in Jesus hand in Revelation 1 to 3 are Clergy. They are the Angels (spirits or souls) of the churches. In both Thyatira and Sardis the leaders are clearly in the wrong. It is up to the members to reform the church or at least stay faithful themselves.
There are two tragic tendencies which work against realising this quality of fellowship. One is ”individualism” - the besetting sin of my culture. The other tendency is putting blood kinship above Christian fellowship which is a common failure where the extended family is more dominant.
To turn back to the positive, the New Birth is what creates spiritual life at both the communal and personal level. It does not just give me a share in the resurrection, it places me into the pattern of obligations and privileges of the church of the firstborn (Hebrews 12:23) (Note the plural – not Christ the firstborn but we who are the firstborn sons of God).
One problem which I have to recognise is the issue of spurious “new births” – people who have prayed a sinner’s prayer or have had a moving experience in church and so declare themselves born again. It can lead to an amoral “gnosticism” and I believe this is far too common. 1 John is in our bibles to deal with this.
I am writing concisely so please forgive the lack of references and argumentation. I am sure readers can fill the gaps.
