As upset as I was, however, I wanted to know why they would want me to sign such a statement, especially when no other such promises were required on any other subject for ordination! Moreover, both the Reform and Reconstructionist movements appeared to have no problem with having interfaith families in their congregations. But apparently, neither thought it acceptable for someone in an interfaith relationship to serve those congregations as a rabbi. I brought the subject up with other members of the Hillel community to hear what they thought could be the reasoning behind the rule.
But can Reform congregations -- or any other congregations -- ever really be welcoming to interfaith families if rabbis in interfaith relationships are forbidden? Would you consider a religion to be "welcoming" to same-sex couples if it refused to ordain someone who was in a same-sex relationship? Probably not.
