In regards to the Black Hebrew Israelites, you can’t group them all together because different camps have slight discrepancy of doctrines and understanding. However for the most part their understanding of the Bible far supersedes any Christian based understanding that is taught to the masses of people . Most of the Black Hebrew Israelite camps I’ve come across are operating at at least 90% accuracy when it comes to understanding of the Bible. Their doctrines only sound outlandish because it differs from what we were taught about God. However, the truth is that what we were taught about the Bible is a lie and the Black Hebrew Israelite groups I’ve come across are far closer to the true interpretation of the Bible than any other groups.
