The talk has been strongest in the Jewish community. There has been more rejoicing than lamenting about this interfaith union that brings a former first daughter a step closer to the fold. Still, they wonder: Has Chelsea been searching for a rabbi along with her gown?
"If they had a Jewish wedding officiated by a rabbi, I think that would be something really positive," said Ed Case, president of InterfaithFamily.com, which supports Jewish outreach to interfaith couples. "It's so important for the Jewish community to have interfaith couples engaging in Jewish life."
Chelsea Clinton grew up attending Methodist church with her mother. Bill Clinton has been close to his pastor in Arkansas, but the Southern Baptist Convention rebuked him years ago over his support for gay relationships and abortion rights.
Last year, Chelsea, a graduate student at Columbia University's School of Public Health, was seen attending Yom Kippur services with Marc at the Jewish Theological Seminary in New York, the flagship for Conservative Judaism, according to news reports.
Mezvinsky is a son of former Pennsylvania Rep. Marjorie Margolies-Mezvinsky and former Iowa Rep. Ed Mezvinsky, longtime friends of the Clintons. His parents, who are divorced, had attended a Conservative Jewish synagogue in Pennsylvania.
Hillary Clinton has strong ties of her own to the Jewish community from serving as a senator from New York.
"She has probably been in more temples by far than either you or I," said Rabbi Jerome Davidson, rabbi emeritus at Temple Beth-El of Great Neck, which Hillary Clinton has visited.
No one is saying, though, what route Marc and Chelsea will take.
That would be nice if they can celebrate both religions. Its important in a multi racial family to keep the traditons of both. This is the same for religious diferences as well as cultural differences. I am proud of Chelsea
