You’ve been quoting 1Cor 1:10 about divisions in Corinth. This maybe the opportunity to answer that question. Why were they quarrelling in Corinth? Was it because of different doctrines? NO! Not at that time. The doctrine is the same but the people in Corinth were having problems on whom to follow as their leaders. They were divided into three or four factions and as a symbol or sign of their pledge or oath to their leader or group the people were baptized into this group headed by the leader they choose.
Paul asked in verse 13 “Is Christ divided?” Are we today? Yes! Because of different doctrines, but have you notice that these Christians in Corinth all have the same doctrines to begin with and they are not yet divided as we are today.
What is your point?
Division is division. Who created the division?.....men. What are "factions"? Sects centred around following men. If they were united in belief then what was the point of following one person as opposed to another as leader?
"The Greek word (
hai′re·sis, from which comes the English word “heresy”) thus translated means “choice” (
Lev 22:18,
LXX) or “that which is chosen,” hence “a body of men separating themselves from others and following their own tenets [
asect or
party].” (Thayer’s
Greek-EnglishLexiconoftheNewTestament, 1889, p. 16) This term is applied to the adherents of the two prominent branches of Judaism, the Pharisees and Sadducees. (
Acts 5:17; 15:5; 26:5) Non-Christians also called Christianity a “sect” or “the sect of the Nazarenes,” possibly viewing it as a break-off from Judaism.—
Acts 24:5, 14; 28:22.
Jesus Christ, prayed that unity might prevail among his followers (
John 17:21), and the apostles were vitally interested in preserving the oneness of the Christian congregation. (
1Cor 1:10; Jude 17-19) Disunity in belief could give rise to fierce disputing, dissension, and even enmity. (Compare
Acts 23:7-10.) So sects were to be avoided, being among the works of the flesh. (
Gal 5:19-21) Christians were warned against becoming promoters of sects or being led astray by false teachers. (
Acts 20:28; 2 Tim 2:17, 18; 2 Pet 2:1) In his letter to Titus, the apostle Paul directed that, after being admonished twice, a man who continued promoting a sect be rejected, evidently meaning that he be expelled from the congregation. (
Titus 3:10) Those who refused to become involved in creating divisions within the congregation or in supporting a particular faction would distinguish themselves by their faithful course and give evidence of having God’s approval. " (Insight Volumes "Sects" WTBTS)
There was to be no division on any basis. Paul made that clear, so where does that leave Christendom? Epic fail!
Are they all one in Christ or “Is Christ divided”? Only God can know this.
We had better know this too or else how would we obey God's command to "get out of Babylon the great" before God brings her to her end? (Rev 18:4, 5) In the harvest time, angels are instructed to gather the "weeds" of false Christianity first and pitch them into the oven for destruction. Then he will gather the "wheat" into his storehouse. That time is rapidly approaching. The angels are ready to reap their harvest.
And this is what the Lord Jesus was saying in John 17:20 ”that they may all be one” as in one Body of Christ. Who placed a True Christian into the Body of Christ? Was it not the Holy Spirit? YES!
1CO 12:12 For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ.
1CO 12:13 For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.
This is what the Lord Jesus Christ was saying in,
ACTS 1:5 for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.”
Baptized with the Holy Spirit into the Body of Christ, and there is only ONE Body of Christ, the True “Church of God which He purchased with His own blood –Acts 20:28”
Actually the Interlinear translates that a little differently......
Acts 20:28
"Watch out for yourselves and for all the flock in which the Holy Spirit has placed you overseers, to shepherd the church of God, which he purchased with the blood of his own Son." (Mounce Interlinear)
Bias towards the trinity in your translation......much? 
Paul's words apply only to those with "the heavenly calling" (Heb 3:1) Not all Christians have "the heavenly calling" for the simple reason that these are chosen by God for rulership with Christ in his kingdom. As "kings and priests" they are not going to rule one another, nor do they need priests because they have left their imperfect flesh behind and are no longer sinners.
So over whom do these ones rule and for whom do they perform their duties as priests?
They need subjects and sinners......who are they? You never answer this.
Now, God/Father unity with His only God/Son is different from their unity with the true believers.
Scripture to back this up please. This is the same oneness......where does it state a different "oneness"?
JN 20:17 Jesus *said to her, “Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren and say to them, ‘I ascend to My Father and your Father, and My God and your God.’ ”
The Lord Jesus Christ said “My Father and your Father and My God and your God”
Jesus is equating his relationship with God to Mary's. He is the same God and Father to Jesus as he is to Mary. How can you not see that?
The Lord Jesus’ union with His Father is as “the only begotten God –John 1:18” while the disciples are through adoptions. “He predestined us to adoption as sons through Jesus Christ –Eph 1:5”, “waiting eagerly for our adoption as sons –Romans 8:23. Read also John 1:12-13.
Exactly. Jesus is the already part of Jehovah's heavenly family because he is the natural "only begotten son" of his Father.
Those who are chosen to be his "brothers" must be "adopted" because one cannot become part of the heavenly family unless they undergo a new birth as spirit beings to dwell in heaven. This is what it means to be "born again"...given a new birth in a completely different body.
What on earth do you believe the reason for going to heaven is? If they are to be "kings and priests" who are resurrected "first", (Rev 20:6) then who are their subjects and who are resurrected after them....and where?
In his Revelation, the apostle John sees the heavenly new Jerusalem "coming down" to rule "men". He then describes the life that humans can expect to live....
..
"Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, “Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God. And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.” Then He who sat on the throne said, “Behold, I make all things new.” And He said to me, “Write, for these words are true and faithful.” (Revelation 21:2-5 NKJV)
There will be a return to God's rulership in the very capable hands of Jehovah's appointed king and his "joint-heirs".
This is the kingdom Jesus told us to pray for. Your version makes no sense at all. You have all chiefs and no Indians.
