The purpose of religion is very practical, to provide its members with a satisfying life. Such a life generally includes a community of people that members can get along with.
If you have found such a religion, then you have no need for Biblic Judaism. If you haven't, then I urge you to consider mainstream religions like Christianity, Islam, and Talmudic Judaism before considering Biblic Judaism. If you have considered mainstream religion and you couldn't find one to suit you, then it is time to consider Biblic Judaism.
Biblic Judaism is moral, reasonable, and non-racist. I believe this makes Biblic Judaism unique. Modern Christianity isn't moral, Islam isn't reasonable, and Talmudic Judaism is racist.
Biblic Judaism will never be a large religion. So it must work even for isolated individuals. Biblic Judaism must provide a reasonable path through life for its members that doesn't depend on achieving a critical mass of Biblic Jews. But then how can it provide a community? The answer is that Biblic Judaism must be designed to leverage existing communities of another religion. Our plan is to leverage Orthodox Judaism based on the fact that at least some synagogues accept Noahides. This is untested, but we will test it soon. If this doesn't work, then we will look at Islam as an alternative.
