An Orthodox rabbi performing a ‘gay marriage’ would cease to be orthodox.
The Council of Torah Sages of Agudath Israel, whose members most have never heard of, actually set the pattern that others follow. They will never accept ‘gay marriage’.
Mizrachis (Religious Zionists), the only ‘orthodox’ that might do this, would transform themselves into the Reform Movement, though the possibility seems remote.
The rabbinate’s silence is a form of acceptance. They should have forcefully come out against this ruling. Watch the homos try and force orthodox rabbis to perform such weddings. Then they’ll have to do something.
