Reply To: Does a Mesora need a Mekor?

Every “mesorah” has a mekor (origin, source), only you may not know it. What makes a “mesorah” (tradition, custom, practice), halachically significant is that over time it has become widely accepted. From a halachic perspective, the relevant “fact” is not an origin that might be unknown (and is of interest to anthropologists and social historians), but the current status of its acceptance.
