Labels are fine IF one is also understanding that one, not hold to every item associated with that label, are not being in the slightest deceitful or underhanded by stating that they are NOT that label.
For example, just because I am a believer in the literal second coming, followed by a literal millennial rule of Christ, and am also hopeful of a rapture, there are some who would automatically want to label me as a "Darby" dispensational thinker.
That label is inaccurate.
Because I am one who considers the church is NOT some "parenthesis," given ONLY to the gentiles as a totally separate group from the believing Israeli, it is wrong to be labeled as a "Darby Dispensationist." Rather, such (imo) unwarranted attempts to scorn and ridicule - to basically show contempt as another poster stated - to present some matter as lesser or unworthy is clearly unethical as well as not the character of a believer according t0 Philippians 2:
Do nothing from selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves; do not [merely] look out for your own personal interests, but also for the interests of others. Have this attitude in yourselves which was also in Christ Jesus...
Admittedly, there are times (far more often than I would care to admit) that I don't set that standard as I post.
To some, labels, such as New Covenant, Dispensation (even Darby Dispensation), Covenant..., are matters of doctrine that rise to the level of heretic and conspiracy. Imo, that type of thinking is askew from the reality of what each represent in this period of time.
Rather, as I posted earlier, various views can be held with the idea that there is some matter of overlap and even agreement; because, as stated earlier, views can be considered merely as a matter of outlining Scripture and presenting a thread of thinking that has both strong and weak points. This is important because ALL when
modified by Scripture can be shown as accurate, yet without that Scripture modification can be seen as highly inaccurate.
There are some areas that should
never be a point of argument and considered as not standing the test of Scripture. These areas should include (but not limited):
1) the typical replacement thinking - that is the church has replaced Israel and that God has no future plans for the national / political group.
2) the typical replacement thinking - that is the church is an interruption, a "parenthesis" in God's scheme brought on by Israel's rejection of the Messiah, or some other contrivance in which the church and the believing Israel are separated into two or more groupings.
3) the typical replacement thinking - that God has repented of, or no longer is held accountable for all His vows between He and the national/political Israel - that God has no regard for them as He once promised.
4) the typical replacement thinking - that God saves people in a different manner or ways at different "dispensations" according to His divine purpose.
None of those four items is Scriptural. To what extent or how much the Scripture is violated by each of those four items perhaps should be a different thread.
