Simply what the title asks, I understand what orthodox requires, I understand what reform requires, but quite frankly im only concerned with what the Bible requires. I understand that orthodoxy largely gets its raison d'être from the Shulchan Aruch and the RamBam's 13 principles of faith, but does that rationale stem from Torah or from somewhere else?

Hope this question makes sense,

thank you,
