The Jewish concept of marriage is based on kiddushin (sanctification). The wife and husband are publicly sanctified to each other in an exclusive relationship. The rules regarding such sanctification, by definition, are for a relationship between the Jews. The Jewish declaration of marriage includes the phrase that the marriage is being carried out by the laws of Moses and Israel; such a declaration has no meaning for a marriage ceremony between a Jew and a gentile. If any such marriage is carried out Jews of course recognize the civil legitimacy of such a ceremony, but accord it no religious legitimacy.
The marriage ceremony used to be one of acquisition. It is based on the rules for transfer of property in biblical times. In marriage, the woman accepts a ring (or something of value) from the man, accepting the terms of the marriage. A marriage contract (ketubah) is read publically. Witnesses are required for both the signing of the ketubah and the ceremony.
In the past, a Jewish marriage could be contracted in three ways: (1) with money (as when a man hands a woman an object of value for the purpose of contracted marriage, and in the presence of two witnesses, and she accepts); (2) through a ketubah (written declaration); (3) or by sexual intercourse, a method strongly discouraged by the rabbinic sages. Today only the marriage ceremony involving the ketubah is practiced.
There is a difference between a religious Jewish marriage and the secular marriage. In the United States (and many other countries), when a rabbi officiates at a wedding, it is de facto a legal wedding by the law of the United States, as well; therefore, a rabbi cannot officiate for you without a civil license. This is the secular (civil) marriage. However, Kiddushin is a ceremony that takes place between two Jews. Most rabbis will not officiate at a wedding between a Jew and a non-Jew because it is outside the realm of Jewish traditional practice.
Under certain circumstances, Reform and Reconstructionist rabbis will officiate at a marriage between a Jew and a gentile, if the couple agrees to bring the children up as Jewish.
