On a February 2007 trip to India, Metzger joined other prominent rabbis in signing a declaration against violence with local Hindu leaders, as part of a summit organized by the World Council of Religious Leaders. One of the points emphasized by the participants was the commonality between Jews and Hindus, particularly in regards to ongoing violence at the hands of Muslims. Metzger noted in his remarks, "Jews have lived in India for 2,000 years, and have never been discriminated against. This is something unparalleled in human history."
