Surely you agree that there are those who belong to the true church and those who are false, making a profession, but yet remaining outside the body of Christ.
You are making a fundemental exegetical error. The Greek term ekklesia was used in Classical Greek and throughout its pre-New Testament history to mean only a local visible assembly of people gathered to conduct some sort of business. It never was used to mean "the called out ones." It was commonly used in the institutional sense in Classical Greek. In the New Testament, one cannot simply tack on a brand new meaning opposite to its whole history of usage until it is proven that its common ordinary concrete and institutional uses do not make sense and there is no passage where either the concrete or the institutional sense does not make sense. The Bible never uses metaphors that convey invisibility or universality in reference to ekkesia. They are metaphors that convey visibleness and locality.
To answer your question, the churches of Christ contain no members who do not profess Christ but do contain lost professors as in the case of Judas. The church and salvation are not synonyms in any context in the New Testament. You believe in church salvation as you have no salvation outside your church and only in your church is salvation - that is fundamentally the Roman Catholic doctrine of church salvation simply revised to "invisible" by Reformed Roman Catholics but both are false doctrines.
When the apostle penned Romans 6, whilst he did not know the hearts of all who made a profession, he knew that those who truly believed were indeed, dead to sin and alive the Christ. My point is simply that one can belong to the body of Christ, be spiritually resurrected, without undergoing the rite of physical baptism.
Romans 6:4-6 is speaking about water baptism not spirit baptism as Spirit baptism portrays or conveys no "likeness" of anything but water baptism does. Moreover, it is water baptism that provides a public "likeness" that repudiates the idea that grace promotes sin because water baptism identifies the believer publicly and openly with both justification or positional deadness to sin by immersion in water as one dead and being buried; and by identification with the resurrected life of Christ, thus identification with regenerative life over which sin has no power. Paul's point is that justification by faith does not occur without or apart from regeneration and it is water baptism that publicly proclaims, affirms and demonstrates this by joining one with the other. Hence, we are dead to sin legally and positionally by the cross, his death and we are dead to sin regeneratively by the resurrection life of Christ, both of which are provided in "likeness" in public water baptism.
The true church consists of all those who are in Christ from Genesis 3:15.
No, it does not! You are teaching the doctrine of Roman Catholocism or church salvation as to be "in Christ" by our doctrine is to be in the church and to be lost by your doctrine is to be outside the church that is Roman Catholicism, the error continued by Reformed Roman Catholics. The church and salvation are not one and the same. For example, your doctrine teaches that entrance into that kind of church is through the baptism in the Spirit, however, there is no baptism in the Spirit prior to Pentecost is there, and therefore no possible entrance into your kind of church for OT saints. Second, Ephesians 2:20 and 1 Cor. 12:28 explicitly repudiate your Old Testament body of Christ church as Paul plainly states that "apostles" are the FIRST God set in His church not Abel, or Abraham.
It is this church that is being conformed to the image of Christ.
No it is the individual believer that is being conformed to Christ (Rom. 8:28-32). The church is the metaphorical body of Christ that is the visible representative of the kingdom of God on earth and administers the ordinances.
Christ is the Head of the church and he is the Saviour of the body.
That is true as one cannot be a member of a New Testament church apart from such a salvation profession and Paul treats the profession as authentic as he was instrumental in constituting the churches he addresses in this manner. The metaphor "head" is NEVER used of anything other than "authority" in Scripture. Christ is the final "authority" over the church and all New Testament churches confess that.
I cannot make a distinction between the true church that consists of those that are truly regenerate and the body of Christ.
The only "true" church are New Testament churches or using the generic or institutional sense "the church" what you have is a false church that has no reality. In reality your concept is a confusion between the church and the kingdom of God and Augustine was responsible in church history for introducing that confusion with the idea of the church simply to escape the doctrine of church discipline.
They are one and the same. I would have no difficult in believing that Abraham was in the church and a member of Christ's body. That he was seated in heavenly places in Christ and a member of the new covenant. It is the the entire church from both before and after Christ's earthly work that is going to be presented without spot or blemish
You are confusing the "family" of God with the "church" of God and they are not one and the same. You have to ignore scriptures, redefine terms, invent a new kind of salvation to produce your concept of the church. For example, your concept requires entrance by the baptism in the Spirit as that is your doctrine modus operandi for placing members into you kind of church but the baptism in the Spirit had no existence previous to Pentecost.[/QUOTE]
