Having been following or been involved with what is now referred to colloquially as the Hebrew Roots Movement (HRM) for better than 30 years I have looked at dozens of teachers. I have rarely known any to embrace quabbalah or talmud. Those that do are usually Messianic Jews. They are NOT the same thing. Having read this thread from beginning to end I must say that few if any of the commenters has a clue about the reality of this movement or its teachings.
For background only I will let you know that I have a PhT from a prominent Southern Baptist seminary. So there is that.
That being said. Most HRM believe salvation is a free gift. The Grace doctrine is alive and well in 99 out of 100 HRM homes. They ALSO believe that reward is by merit. This belief is held as well by most mainstream proteatant denominations. So there THAT is. where the major disconnect for most Christians trying to understand HRM is simply the Nature and definition of sin. And the understanding of the teachings of Paul and Messiah on this subject.
Even in my Baptist schooling I was taught you have to read Peter In order to read Paul. So here is some Peter for you 2Peter3 starting in verse 15:
15 and reckon the patience of our Master as deliverance, as also our beloved brother Paul wrote to you, according to the wisdom given to him,
16 as also in all his letters, speaking in them concerning these matters, in which some are hard to understand, which those who are untaught and unstable twist to their own destruction, as they do also the other Scriptures.
17 You, then, beloved ones, being forewarned, watch, lest you also fall from your own steadfastness, being led away with the delusion of the lawless,
18 but grow in the favour and knowledge of our Master and Saviour יהושע Messiah. To Him be the esteem both now and to a day that abides. Amĕn.
From there you should figure out the definition of sin. 1John 3:4 has that definition in the Greek Scriptures if you do not believe in the Hebrew Scriptures. It reads as follows:
1John3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Now your starting to see the base of the HRM.
Another thing you should watch is

This is a relatively new teacher who lays it out plainly with loads of (mainly) NEW TESTAMENT verses.
Perhaps the believers here could see what HRM actually believe before bearing false witness of fellow believers. Frankly I have never met a single HRM believer who discounted Messiah or put more weight on the law than Grace and I probably know many more than most folks commenting. Messiah's love and Grace to you all.
Shalom
