Rav Siach is the Hebrew word for a multi-party discourse, and it is the name chosen for a program initiated by the Masorti Movement in Israel and the Ministry of Diaspora Affairs, designed to provide Conservative Masorti congregations worldwide and Masorti communities in Israel with a platform which would enable them to connect and form relationships between Israeli and Diaspora rabbis and their respective communities.

Rav Siach aspires to cultivate a dialogue between the communities, which will grapple with key issues confronting Israeli society and Diaspora communities.

The program is largely centered on communication between the participating rabbis and congregations, developing educational content about Israel, Israeli society, Israeli culture, the Israeli-Jewish calendar, Jewish life-cycle, etc.
