By what authority does Rabbi Ba'avad have the right to speak on behalf of "every Jew"? Was there a vote that I missed? Or perhaps the Lord Himself told Ba'avad that he was in charge (although He apparently neglected to inform anyone else on this decision). Now, I can only claim to speak for myself, but this particular Jew has ZERO interest in the restoration of animal sacrifices. I'll stick to the customs of the last 2000 years and just go to shul on Yom Kippur, thank you very much.
According to the customs of the last 2000 years, Jews attend shul more frequently than once a year.
