The move's opponents, led by Israel's chief rabbis, are seeking to increase the pressure on Prime Minister Benjamin Netanyahu in a bid to prevent the conversion law initiated by Knesset Member Elazar Stern of Hatnua faction.
Following the disagreement over the bill within the coalition, Netanyahu plans to bring the issue to the cabinet meeting next week as a government decision, thereby avoiding legislation. But the ultra-Orthodox parties and conservative circles within the Religious Zionism movement with to thwart that move too, and have now gained support overseas.
Ashkenazi Chief Rabbi David Lau visited Britain this week to discuss the crisis with the participants of a rabbinical conference in London. Following what he heard from the rabbis, he warned against a rift between Israel and Jewish communities around the world.
According to Rabbi Lau, the leaders of the London Beth Din had told him that they would not be able to recognize official conversion certificates from Israel.
"The world's rabbis always believed that the State of Israel would protect this important and sensitive issue of conversion more than any other state," Rabbi Lau said. "They never believed that they would have to consider whether to recognize conversion certificates arriving from Israel."
'Government taking a very dangerous step'
The chief rabbi was asked to relay a message from three senior religious judges – Rabbi Chanoch Ehrentreu, Rabbi Aharon Yitzchok Binstock and Rabbi Menachem Gelley – that they "deeply fear and are extremely concerned" by MK Stern's proposal.
"They expressed their shock over the expropriation of responsibility for conversions from Israel's Chief Rabbinate," he said.
Rabbi Lau has turned to the prime minister together with Sephardic Chief Rabbi Yitzhak Yosef, demanding that the move be stopped. He says he has heard similar reactions from rabbis in other countries, and he understands them.
"The government is taking a very dangerous move here," he said. "We are headed towards a dangerous and irresponsible direction for the State of Israel's Jewish future.
Rabbi Lau concluded by stating that just like significant moves are not led without being coordinated with the relevant ministries, the conversion issue cannot be advanced without the Chief Rabbinate's consent and while ignoring its halachic opinion.
