Can you cite any Torah authorities outside of the Temple Institute who support their activities?
Rabbinical Council of America? Agudath Israel of America or of Israel? Shas? Chief Rabbis of Israel?
Why? Are more required for the work to be progressing? My point was made that work and planning is going on re the rebuilding of the Temple. Would you say that all denominations should be involved for something to be correct or done in Christendom?
