In his book, Till Faith Us Do Part, (1996) Rabbi Jonathan A Romaine considers attitudes to mixed race marriages. His study was focussed in Britain, however there is likely to be general global relevance. He states that Christians, Hindus, Muslims,Jews, Sikhs, who fall in love with one another may retain a deep respect for the views of their families and the requirements of their faiths. However, in many cases, emotions now take precedence over religious traditions. This, he says, would have been less likely in former years. In contrast, there is no issue with mixed faith marriages in Buddhism.
“A Fish and a bird can fall in love,
but where will they build their home?“
