Ideas about the Kingdom of the Heavens around us and the unity of believers in Christ within it
Korah’s rebellion was to insist on half the truth–that all in the congregation of Israel were holy, set apart to God, because the Lord was among them–but to reject the other half–that only the Lord had the right to assign each their functions. They denied this half of the truth to rebelliously assert their own authority, as false teachers today also do.
Jude’s description of divisive persons in the church points to false believers who try to look like us but have infiltrated the church for their own advantage, to serve their own greed and lusts. They are dead trees, and dead trees bear no fruit. In dealing with them, we need to contend for the truth and resist contending against them personally.
1 Timothy 6 also warns about people who create arguments in order to exploit them for financial gain and to build their own authority. This warning is presented in the context of teaching about respect for human authority and authority in the Church.
Like Balaam, false teachers do their work stealthily motivated by greed. They do not openly deny the Lordship of Christ, but deceptively proclaim teachings that permit us to retain our own independence, greed or lust, to seek first our own pleasure, and still, they say, please God. They teach these things not necessarily because they believe them, but to obtain our following and our money.
Peter’s main points in 2 Peter 2 regarding false teachers teaching heresies is that these teachers act stealthily, are motivated by greed, and use their teachings to create a lucrative following.
Titus 3:10 instructs whenever a divisive person approaches ME and tries to start an argument, I am to warn them twice about their behavior and then excuse myself. Thereafter I should ignore them, until they repent of their argumentativeness. It is a simple instruction by which I can avoid being influenced by divisiveness. It is not an instruction to the Church or the State to burn heretics.
In Galatians 5:17-23, “heresies” are one of the works of the flesh–something we do, not something we believe. These works are opposed by the fruit of the Spirit.
Factions, “hereseis,” as used in 1 Corinthians 11:19, clearly does not refer to divisions caused by false teachers. Instead, in that context, it refers to divisions caused by neglect and humiliation of poor believers and by the formation of personality cults.
The words “heretic” and “heresy” in English New Testament translations are actually transliterations of Greek words that primarily denote division or divisiveness. They are used with those primary meanings in Acts. They did not come to secondarily connote teaching,teachers or doctrines disapproved by a church organization until the late second century. Tha authors of the New Testament did not know of this later technical meaning.
Heresy is properly defined as divisiveness, not merely believing a false doctrine. Heretics are divisive people. Those who state doctrines with which I disagree, but do so without insisting on division because of my belief, are not heretics. Thus calls for mutual understanding and patience.
