Many people are quick to yell, "Don't judge me!" whenever someone attempts to tell them they are off the mark in some way. Truth is,TORAH is our judge. We're not "judging" anyone by telling them that they're going against Torah principles..
"Judging" refers to the attempts to correct others according to your own standard of iniquity. When you do that, you condemn yourself. When you "judge", you must do it SOLELY by the standard of truth, and that truth (which Paul amply addressed in Romans 2:1-8) is Torah.
So, the bottom line is, when Torah observant Believers see, someone teaching "no need for Yeshua," for instance, or "no need for Torah," or anything else that is contrary to Scripture, we MUST rebuke them! To sit idly by and say nothing is NOT an option, for if we don't help our brethren stay on the YHWH's Path, then WE will be held accountable! (See Ezekiel 33, James 5:19, Matthew 18:6, Acts 20:28, etc.)
Also consider this:
Titus 1: 13. And this testimony is true. Therefore rebuke them sharply that they may be sound in the faith 14. and may not throw themselves into Jewish fables and into the precepts of men who hate the Truth. 15. For to the pure, everything is pure; but to them who are defiled and unbelieving, nothing is pure; but their understanding is defiled, and their conscience. 16 And they profess that they know Elohim, but in their works they deny him; and they are odious and disobedient and to every good work reprobates. (AENT)
What then are these “Jewish fables”?
“According to Charles Ryrie: Jewish myths; speculations of a Gnostic sort, supposedly based on OT scripture. Ryrie Study Bible (NASB), p. 393. The key is in the highlighted portion of the above passage, “they profess to know Elohim, but in works deny him” for by this very description,
Paul has named the heretical sect. “Gnosticism” is derived from the Greek gnosis, “to know.” What is often overlooked is that Gnosticism did not originate with Christianity, although later adopted by many Messianic themes. Rather, it began as a Jewish sect with their own “myths and fables.” According to Professor Ryrie: The heresy of Gnosticism had begun to make inroads among churches in John’s day.
Among its teachings were: (1) knowledge is superior to virtue; (2) non-literal sense of Scripture is correct and can only be understood by a select few; (3) evil in the world precludes God being the only creator; (4) the incarnation is incredible because deity cannot unite itself with anything material such as a body (Docetism); and (5) there is no resurrection of the flesh. The ethical standards of the Gnostics were low… (Ryrie Study Bible (NASB), p. 440).
Is it any wonder then why Paul was upset at these false teachers? Even a conventional Pharisee would take great offense to such posturing, and they most certainly did with four of these five articles of belief. These false teachings are, of course, diametrically opposite to Paul’s own teaching as a “ringleader” of the Netzarim, so there should be no surprise when he takes these false teachings to task.
In any case, one can easily see how modern readers, divorced from the historical context, can easily draw the wrong conclusion and not take into account who the speaker is, and who the intended audience is.” (Source, AENT)
