I saw it somewhere online. I believe it was attributed to the Lubavitcher Rebbe.
One final question (and please forgive me for being so much trouble on such a busy day): could the qorban pesach be offered according to the current, fixed calendar, or would the date of the new moon have to be established by the testimony of two witnesses?
I’m hardly an expert. But I don’t think you’d need the testimony of two witnesses, which would require a Sanhedrin.
