Thanks for responding MrW. I know how to define the church but the divide between theological systems is largely (imo) due to the fact that it is misunderstood by most people. That is understandable because God calls it a "mystery" revealed by the Spirit first to the apostles and the prophets somewhat piecemeal but later to the specially chosen man, Paul, who God would commission as the lone apostle to the gentiles, whom he began adding to the church some 10 years after it's beginning on Pentecost with Israel only. Paul was different in that he was given complete understanding of the church of Jesus Christ.
Now, here is an example of the piecemeal revelation in the primitive church before most of the NT epistles were written.
.
1 Cor 14:23 If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that ye are mad?
24 But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all:
25 And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.
26 How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.
27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
28 But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.
29 Let the prophets speak two or three, and let the other judge.
30 If any thing be revealed to another(prophet) that sitteth by, let the first (prophet) hold his peace.
31 For ye (prophets) may all prophesy one by one, that all may learn, and all may be comforted.
32 And the spirits of the prophets are subject to the prophets.
33 For God is not the author of confusion, but of peace, as in all churches of the saints.
This is how the truths were disemminated in the churches before the written scriptures.
Check this out.
1 Cor 12:27 Now ye are the body of Christ, and members in particular.
28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.
29 Are all apostles? are all prophets? are all teachers? are all workers of miracles?
30 Have all the gifts of healing? do all speak with tongues? do all interpret?
31 But covet earnestly the best gifts: and yet shew I unto you a more excellent way.
This is the primitive church. The modern church does not have these special spiritual gifts. We cannot even define some of them, like the gift of faith. We do not need them. We have the complete scriptures for our faith and practice. There has not been the exercise of a single one of these gifts since the end of the apostolic era of the church of Jesus Christ. The scriptures alone are our authority, taught by the indwelling Spirit.
I would like to know how YOU define the church of Jesus Christ. I will give my definition later.
