I can give you a personal example of a split with in our family
We were eating lunch one day and my adopted son's birth uncle(also MJ) was having a beef, bean and cheese burrito with us(kosher according to us and our congregation/ most MJs)
After a couple bites he asked if there was cheese, I said yes and he jumped to his feet, ran to the kitchen sink and spit it out and rinsed his mouth like he had just contacted poison:o
Their congregation does not mix meat and dairy....clearly a problem
But to our amaisment it was sooooo much a problem we have never eaten a meal with them again
They cant eat a thing at our house now as even the dishes we serve food on are contaminated because of the non separation of meat and dairy
Where before we saw them a lot, I haven't seen them in sooooo long now which is sad since we adopted the family's daughter's baby and knowing them had been such a blessing to my son
We were hurt and confused as most MJ congregations don't practice that halaka and why were they choosing that over relationship with us.....but
Before had we done that too? Yes many times with kosher food vs unclean food( pork/ shellfish)...I had refused to eat at all my chicken cob salad served with real bacon bits that my mom made for me on my birthday and only had birthday cake that night, or there was a chicken asian dish with some oyster plum sauce at niece's graduation dinner

that they had paid for

We let what folks served at events( family included ) get in the way of fellowship and relationships...can you see the dilemma for Gentiles coming into Torah Teaching with the Jewish culture
It can become a tangled web of issues from what catsup you eat and does your chicken sausage have the right casing. Is that burger fried on the same grill as those pork ribs over there, were these refried beens on my plate made with lard or a vegetable based grease
Most congregations are not looking for strictness and the third degree even though they are Torah therefore Kosher observant, for them its a don't ask don't tell situation. But some do require strictness and that can begin to affect relationships with the world and all Christian / Jewish/ MJ interaction too
Thats why you see the label legalistic thrown in MJ's faces.
Knowing how hurt I was at our own family situation with the meat/milk thing, I can definitely see why folks would resort to name calling and fighting over the Bible and the creation of sects / denominations when it comes to halaka
It really does separate friends and families and communities
Thats is just one example where I have been on both sides of the fence with halaka
Hellenized Jews and Christian Gentiles were solving the problem but not in a good way because they broke off completely from the Jews and created something that wasn't there before, just to keep fellowship going where strained relationships were forming now that this new Torah lifestyle was surfacing. Also the Jews didn't make it easy to transition in either ...can you imagine never seeing your family again because of that region's ( house rules)..
It was wisdom for the disciples to have a few house rules(halaka) for them to follow and allow the Torah teaching to change them as the Word became alive to them gradually
And the eating thing especially was as much an issue then as now as many Christians were judged unclean(as bad as being unsaved/pagan) based on what was in them( food wise) or where they had gotten their last(often clean) meal ( the place). Sooooo instead of judging food Kosher /clean or not it was the person who was unclean or not..... even with the Spirit of God living inside them ....simply because the place that served their Kosher meal bought their beef from pagan Pete's not from a kosher butcher
Its reallllly messy business, and thats why I said I wish all folks coming into this would feel the freedom to understand the Torah first and not accept it blindly because their Torah teacher said so
If it doesnt feel right hold off till it does as we are not talking a salvation issue here...All MJs will attest to that

.....It is an obedience issue sure but as you can see, there are stumbling blocks everywhere and if you don't know the Word in these areas soundly you could be mistaking the house rules of your small corner shul as a true Torah command.
Ohhh and to solve the issue of meat and milk with your Orthodox Jewish /MJ friends...eat out( vegan is good

) or at their place and order what their having....its alot easier

And nooooo casseroles
Makes sense. You have a gift for making things clear.
1. "TORAH keeping is keeping covenant. TORAH breaking is breaking covenant. "
2. "When it comes to doctrine, the correct answer is provided by Tradition, but even if you happen to disagree with the Traditional doctrine (regarding some invisible issue), it does not matter, for your disagreement only enters the realm of reality if it starts to affect praxis, halaka, lifestyle."
3. "Jews would really only split or break with each other over matters of halaka, matters of how to live your life and keep mitzvot."
Praxis - practice, as distinguished from theory. The gap between theory and praxis, text and world". Accepted practice or custom. "patterns of Christian praxis in church and society"
Halacha - Jewish law and jurisprudence, based on the Talmud.
Mitzvot - commandments, traditionally understood to come from God and to be intended for the Jewish people to observe. Those of us who live in the western world are often uncomfortable with the idea of being “commanded” to do something, because it seems to deprive us of the right to choose how we behave.
1. What's an example of something Jews have split over?
2. Have they split with MJ's over any Halacha?
