What faith does Scripture teach?
Seriously, stop and think about that for a moment... Is it Judaism? Is it Christianity? Is it some sort of hybrid?
Let's clear something up: Scripture does not advocate for a Jewish faith or for modern Christianity. While they are both based on certain portions of Scripture, neither is the faith taught by the Bible.
I know that sounds hard to believe and really harsh. But YHWH does not call his people "Christians," and he does not call them "Jews." He calls his people Hebrews and he calls them Israel.
Please note: I am not saying that if you identify as Christian or Jewish your faith is not sincere or that you are not saved, etc. Your salvation is between you and YHWH. I don't believe any of us have perfect theology and don't see that as a prerequisite for eternal life.
In the "Hebrew roots" movement, there is often an emphasis on restoring the 'Jewishness of Jesus.' As you may know, what people typically mean by that is observing the Sabbath day and feasts, as well as not eating pigs or shellfish, and maybe even learning a few Hebrew words. And those are all great things! But saying that the Messiah did these things only because he was 'Jewish' creates a lot of confusion.
Have you ever thought about keeping the Sabbath or another Biblical instruction and then written off doing it because you aren't Jewish? Have you ever shared with someone about following Scripture's instructions and have them reply that they aren't Jewish so they don't have to do that? The misconception that these are "Jewish" things comes from this misnomer of the 'Jewishness of Jesus.' He was from the tribe of Judah, yes, but he is a Hebrew!
Now please hear me: I am not saying that those in Judaism aren't sincere in their faith. I am not saying that every single Jewish person abides by the entire Talmud. I am not passing judgment on anyone's sincerity or relationship with God. But I am not going to turn a blind eye to contradictions between this faith system and what Scripture teaches. It is incorrect to say that Judaism is just the faith of the Old Testament still waiting for the Messiah, when so much has been added to it. It is worth noting that Yahusha never once described himself as Jewish, and that Apostle Paul described Judaism as his former way of life (Galatians 1:13).
While Judaism tends to add things to Scripture, Christianity often takes things away. Not necessarily by actually removing verses from Bibles (Though that is a problem, and versions of Scripture are actually printed now that have removed all verses on homosexuality, for example.), but by a wholesale writing off of much of what Scripture teaches. Mainstream Christianity teaches that we shouldn't keep many of the commandments found in Scripture, including: not bringing YHWH's name to nothingness, honoring the Sabbath, instructions for how we should eat, laws related to hygiene, and celebrating the set apart times. I understand the argument against these things (and believed it myself for much of my life), but that simply doesn't hold up with a deep examination of Scripture. Furthermore, nowhere in Scripture are we given license to disregard the instructions on how to live.
The Hebrew faith is different from both Christianity and Judaism. It's where we take the whole of Scripture seriously, without adding to it. We need to divide it rightly so that we understand what the faith of the Bible really is. While there is common ground to Christianity and Judaism, our faith shouldn't be a hybrid of two flawed religious systems.
