Reply To: Techeiles 🔵❎🐌☑️🐟

In summary:

Let’s say we grant that it’s possible that “The Mesorah” is against Techeiles and it’s possible that “The Mesorah” is not against Techeiles. Now we have a shaila about wearing Techeiles. The rule of safek d’oraisa l’chumra posits that the burden of proof is on you to PROVE that we should not do the mitzva. We do not have to PROVE that we should do the mitzva because by a mitzva d’oraisa the default position is if we can’t prove either way then you have to do the mitzva. Therefore, the burden of proof is on you to prove that “The Mesorah” is against Techeiles. Until then, safek d’oraisa l’chumra prevails.
