Three kinds of church ...
the scripture distinguishes three kinds of church since the establishment of the new covenant ...
To understand this poorly understood point, begin with the new covenant itself [Hebrews 8:8-12, Jeremiah 31:31-34]
Heb 8:11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
This statement is not taught in the mass churches of modern religion , since they indeed teach folks who are supposedly under grace , in 'priest schools' ... in place of God teaching all who are under the new covenant as is stated in the new covenant [above quote]
We thus have the position that true saints never teach saints because God |Himself has done so through the holy spirit of truth promised to all true followers of Jesus [e.g. John 16:13]
saints have to teach sinners though and are qualified to do so because they know the truth from God...
so that is the fist two kinds of congregation ... sints with saints , where no-one teaches anyone
and saints when they teach sinners the truth of God...
but there is another widespread type of church where sinners teach sinners , authorised by powers of this earth , but claiming that God authorised them...
three types of church then . the third type the churches of Satan but pretending to be churches of God :-
1 John 3:8 He that committeth sin is of the devil;
Jesus names the seven churches of saints of God in his Revelation , and it is significant that the chuches of sinners survived whilst every singly church bulding named by Jesus as holy was razed to the ground long ago, and there has beenn no re-assembly of saints there since [the saints are charged with finding the lost House fo Israel by Jesus, a worldwide search , and we know form Jesus that there are about two thousand only on average , alive at any one time , to carry out this sacred task of finding the children of Israel [most not Jews , but the idol-worshipping lost House of Israel scattered long before the Jews were amongst all nations ] amongst the gentiles , for the House of Israel disappeared as a nation, unlike the House of Judah which became visible Israel, the 'Jews'.
Thus one is extremely unlikely to come across any meeting of saints by two or three unless one is one of the very few, the 144,000 sealed by God as firstfruit saints of the new covenant [Rev 7:3-8]
Thus the congregation of God will never be attended by one unless one is a saint...
We may thus continue considering the two remaining types of church....
Paul for instance was NOT sent to find the house of Israel , but to teach the gentiles about the House of Israel and the Jews, a very different role than that of the disciples , though slightly overlapping as the disciples cannot help teaching some gentiles in their search for the house of Israel, and Paul clearly came across a few saints in his mission to educate the gentiles...
but here's the main point, at no time are sinners authorised by god to teach sinners as in almost every church of mass religion today... churches run by thse who sin are of the devil , albeit not satanism as such, but the devil pretending to be holy, righteous :-
1 John 3:8 He that committeth sin is of the devil
2 Corinthians 11:14 And no marvel; for Satan himself is transformed into an angel of light.
15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
This explains what is otherwise mystifying, how modern mass 'Christianity' became so divided when it is supposed to be led in one truth by the spiritof truth of God...
Clearly religion today is divided right down to individual beliefs at every level in the false hierachy [Jesus said he alone is head of his church and no-one else leads it... religion not only has men pretending to be in place of Christ and men calling themselves 'father', 'rabbi', 'vicar' , etc in direct disobedience to Jesus ,but is not united in one belief as the saints are ...]
Now the saints were killed and scattered when they tried to congregate ... Paul's churches were taken over by sinners keeping Sundays and other pagan days in place of holy sabbaths [whilst paradoxically claiming they need to keep no days !]
That leaves us only with churches led by sinners wjho are in turn led by Satan in disguise as a false Christ image , until Satan is ready to confess that he believes he is god [2Thess 2:4]
Te the grand delusion of billions is explained, for not only did the churches of Satan trial and perfect the love of saints by persecuting saints [to death mostly], but Satan would never confess until all teh word worships him (bar a few saints , which he can behead as 'heretics' to his religion ,if he can find them) - Rev 13:3-4
Revelation 20:4 And I saw thrones, and they sat upon them, and judgement was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
