In a move bound to draw opposition from the Orthodox establishment, feminist activists are planning to hold a first-ever priestly blessing ceremony at the Wailing Wall for and by women.

The event, scheduled to be held during the Passover holiday, is being organized by Women of the Wall, the multi-denominational prayer group that holds a monthly prayer service at the Jewish holy site. The blessing will be led by women who trace their lineage to the priestly class known as the “cohanim.” …

The Women of the Wall event is being held in collaboration with the estate of the late Leonard Nimoy, the Jewish actor best known for his role as Spock, the half Vulcan character in Star Trek who popularized the priestly gesture in his famous salute. Nimoy died last year.

Funding provided by the Susan Bay Nimoy and Leonard Nimoy estate is meant to help Women of the Wall advertise the event as well as bus in women from around the country so that they can attend at no cost.
